CLI
Local set up
Once hudi has been built, the shell can be fired by via cd packaging/hudi-cli-bundle && hudi-cli-with-bundle.sh or packaging/hudi-cli-bundle/hudi-cli-with-bundle.sh.
Hudi CLI setup
In release 0.13.0 we have now added new way of launching the hudi cli, which is using the hudi-cli-bundle script.
Note: The traditional hudi-cli.sh script has been deprecated and replaced with hudi-cli-with-bundle.sh from 1.0.2 release onwards. Users should migrate to the new bundled CLI script hudi-cli-with-bundle.sh for better compatibility and ease of use.
There are a couple of requirements such as having spark installed locally on your machine.
It is required to use a spark distribution with hadoop dependencies packaged such as spark-3.5.4-bin-hadoop3.tgz from https://archive.apache.org/dist/spark/.
We also recommend you set an env variable $SPARK_HOME to the path of where spark is installed on your machine.
One important thing to note is that the hudi-spark-bundle should also be present when using the hudi-cli-bundle.
To provide the locations of these bundle jars you can set them in your shell like so:
export CLI_BUNDLE_JAR=<path-to-cli-bundle-jar-to-use> , export SPARK_BUNDLE_JAR=<path-to-spark-bundle-jar-to-use>.
For steps see below if you are not compiling the project and downloading the jars:
- Create an empty folder as a new directory
- Copy the hudi-cli-bundle jars and hudi-spark*-bundle jars to this directory
- Copy the following script and folder to this directory
packaging/hudi-cli-bundle/hudi-cli-with-bundle.sh
packaging/hudi-cli-bundle/conf . the `conf` folder should be in this directory.
- Start Hudi CLI shell with environment variables set
export SPARK_HOME=<spark-home-folder>
export CLI_BUNDLE_JAR=<cli-bundle-jar-to-use>
export SPARK_BUNDLE_JAR=<spark-bundle-jar-to-use>
./hudi-cli-with-bundle.sh
Base path
A hudi table resides on DFS, in a location referred to as the basePath and
we would need this location in order to connect to a Hudi table. Hudi library effectively manages this table internally, using .hoodie subfolder to track all metadata.
Using Hudi-cli in S3
If you are using hudi that comes packaged with AWS EMR, you can find instructions to use hudi-cli here. If you are not using EMR, or would like to use latest hudi-cli from master, you can follow the below steps to access S3 dataset in your local environment (laptop).
Build Hudi with corresponding Spark version, for eg, -Dspark3.5
Set the following environment variables.
export AWS_REGION=us-east-2
export AWS_ACCESS_KEY_ID=<key_id>
export AWS_SECRET_ACCESS_KEY=<secret_key>
export SPARK_HOME=<spark_home>
export CLI_BUNDLE_JAR=<cli-bundle-jar-to-use>
export SPARK_BUNDLE_JAR=<spark-bundle-jar-to-use>
Ensure you set the SPARK_HOME to your local spark home compatible to compiled hudi spark version above. One important thing to note is that the hudi-spark-bundle should also be present when using the hudi-cli-bundle.
Apart from these, we might need to add aws jars to class path so that accessing S3 is feasible from local. We need two jars, namely, aws-java-sdk-bundle jar and hadoop-aws jar which you can find online. For eg:
wget https://repo1.maven.org/maven2/org/apache/hadoop/hadoop-aws/3.3.4/hadoop-aws-3.3.4.jar -o /lib/spark-3.5.4-bin-hadoop3/jars/hadoop-aws-3.3.4.jar
wget https://repo1.maven.org/maven2/com/amazonaws/aws-java-sdk-bundle/1.12.262/aws-java-sdk-bundle-1.12.262.jar -o /lib/spark-3.5.4-bin-hadoop3/jars/aws-java-sdk-bundle-1.12.262.jar
Note: These AWS jar versions below are specific to Spark 3.5.4 and Hadoop 3.3.4
export CLIENT_JAR=/lib/spark-3.5.4-bin-hadoop3/jars/aws-java-sdk-bundle-1.12.262.jar:/lib/spark-3.5.4-bin-hadoop3/jars/hadoop-aws-3.3.4.jar
Once these are set, you are good to launch hudi-cli and access S3 dataset.
./packaging/hudi-cli-bundle/hudi-cli-with-bundle.sh
Using hudi-cli on Google Dataproc
Dataproc is Google's managed service for running Apache Hadoop, Apache Spark, Apache Flink, Presto and many other frameworks, including Hudi. If you want to run the Hudi CLI on a Dataproc node which has not been launched with Hudi support enabled, you can use the steps below:
These steps use Hudi version 1.1.1. If you want to use a different version you will have to edit the below commands appropriately:
- Once you've started the Dataproc cluster, you can ssh into it as follows:
$ gcloud compute ssh --zone "YOUR_ZONE" "HOSTNAME_OF_MASTER_NODE" --project "YOUR_PROJECT"
- Download the Hudi CLI bundle
wget https://repo1.maven.org/maven2/org/apache/hudi/hudi-cli-bundle_2.12/1.1.1/hudi-cli-bundle_2.12-1.1.1.jar
- Download the Hudi Spark bundle
wget https://repo1.maven.org/maven2/org/apache/hudi/hudi-spark3.5-bundle_2.12/1.1.1/hudi-spark3.5-bundle_2.12-1.1.1.jar
- Download the shell script that launches Hudi CLI bundle
wget https://raw.githubusercontent.com/apache/hudi/release-1.1.1/packaging/hudi-cli-bundle/hudi-cli-with-bundle.sh
- Launch Hudi CLI bundle with appropriate environment variables as follows:
CLIENT_JAR=$DATAPROC_DIR/lib/gcs-connector.jar CLI_BUNDLE_JAR=hudi-cli-bundle_2.12-1.1.1.jar SPARK_BUNDLE_JAR=hudi-spark3.5-bundle_2.12-1.1.1.jar ./hudi-cli-with-bundle.sh
-
hudi->connect --path gs://path_to_some_table
Metadata for table some_table loaded -
hudi:some_table->commits show --limit 5
This command should show the recent commits, if the above steps work correctly.
Connect to a Kerberized cluster
Before connecting to a Kerberized cluster, you can use kerberos kinit command. Following is the usage of this command.
hudi->help kerberos kinit
NAME
kerberos kinit - Perform Kerberos authentication
SYNOPSIS
kerberos kinit --krb5conf String [--principal String] [--keytab String]
OPTIONS
--krb5conf String
Path to krb5.conf
[Optional, default = /etc/krb5.conf]
--principal String
Kerberos principal
[Mandatory]
--keytab String
Path to keytab
[Mandatory]
For example:
hudi->kerberos kinit --principal user/host@DOMAIN --keytab /etc/security/keytabs/user.keytab
Perform Kerberos authentication
Parameters:
--krb5conf: /etc/krb5.conf
--principal: user/host@DOMAIN
--keytab: /etc/security/keytabs/user.keytab
Kerberos current user: user/host@DOMAIN (auth:KERBEROS)
Kerberos login user: user/host@DOMAIN (auth:KERBEROS)
Kerberos authentication success
If you see "Kerberos authentication success" in the command output, it means Kerberos authentication has been successful.
kerberos kdestroy is the counterpart: it logs the login user out of the keytab and resets the cached
UserGroupInformation, which is what you want before authenticating as a different principal in the same session.
It only does so when that user holds Kerberos credentials; otherwise it prints Currently, no user login with kerberos, do nothing and leaves the session alone.
hudi->kerberos kdestroy --krb5conf /etc/krb5.conf
Destroy Kerberos authentication
Parameters:
--krb5conf: /etc/krb5.conf
Current user: user (auth:SIMPLE)
Login user: user (auth:SIMPLE)
Destroy Kerberos authentication success
--krb5conf defaults to /etc/krb5.conf. If no user is currently logged in with Kerberos, the command prints
Currently, no user login with kerberos, do nothing and still reports success, so it is safe to run twice.

Metadata for table trips loaded
Once connected to the table, a lot of other commands become available. The shell has contextual
autocomplete help (press TAB), and help lists every command your build actually carries. The
Command reference below documents all of them with their options.
Inspecting Commits
The task of upserting or inserting a batch of incoming records is known as a commit in Hudi. A commit provides basic atomicity guarantees such that only committed data is available for querying. Each commit has a monotonically increasing string/number called the commit number. Typically, this is the time at which we started the commit.
To view some basic information about the last 10 commits,
hudi:trips->commits show --sortBy "Total Bytes Written" --desc true --limit 10
________________________________________________________________________________________________________________________________________________________________________
| CommitTime | Total Bytes Written| Total Files Added| Total Files Updated| Total Partitions Written| Total Records Written| Total Update Records Written| Total Errors|
|=======================================================================================================================================================================|
....
....
....
At the start of each write, Hudi also writes a .inflight commit to the .hoodie folder. You can use the timestamp there to estimate how long the commit has been inflight
$ hdfs dfs -ls /app/uber/trips/.hoodie/*.inflight
-rw-r--r-- 3 vinoth supergroup 321984 2016-10-05 23:18 /app/uber/trips/.hoodie/20161005225920.inflight
To list all inflight and requested instants that have been running longer than a specified number of minutes, use commits show_inflights:
hudi:trips->commits show_inflights --lookbackInMins 30
This lists every inflight or requested instant whose requested timestamp is older than 30 minutes, showing the commit time, action type, and current state. This is useful for detecting hung or stuck writes. The --lookbackInMins option defaults to 0 (returns all inflight/requested instants).
Drilling Down to a specific Commit
To understand how the writes spread across specific partiions,
hudi:trips->commit showpartitions --commit 20161005165855 --sortBy "Total Bytes Written" --desc true --limit 10
__________________________________________________________________________________________________________________________________________
| Partition Path| Total Files Added| Total Files Updated| Total Records Inserted| Total Records Updated| Total Bytes Written| Total Errors|
|=========================================================================================================================================|
....
....
If you need file level granularity , we can do the following
hudi:trips->commit showfiles --commit 20161005165855 --sortBy "Partition Path"
________________________________________________________________________________________________________________________________________________________
| Partition Path| File ID | Previous Commit| Total Records Updated| Total Records Written| Total Bytes Written| Total Errors|
|=======================================================================================================================================================|
....
....
FileSystem View
Hudi views each partition as a collection of file-groups with each file-group containing a list of file-slices in commit order (See concepts). The below commands allow users to view the file-slices for a data-set.
hudi:stock_ticks_mor->show fsview all

Statistics
Since Hudi directly manages file sizes for DFS table, it might be good to get an overall picture
hudi:trips->stats filesizes --partitionPath 2016/09/01 --sortBy "95th" --desc true --limit 10

hudi:trips->stats wa

Archived Commits
In order to limit the amount of growth of .commit files on DFS, Hudi archives older .commit files (with due respect to the cleaner policy) into a commits.archived file. This is a sequence file that contains a mapping from commitNumber => json with raw information about the commit (same that is nicely rolled up above).
Archival normally runs inline with writes. trigger archival runs it on demand, as a Spark job, for the table you are
connected to. The retention options mirror the write configs of the same name, so passing nothing here archives with
Hudi's defaults rather than with whatever your writer is configured to use.
hudi:trips->trigger archival --minCommits 20 --maxCommits 30 --commitsRetainedByCleaner 10 --enableMetadata true
Archival successfully triggered
| Option | Default | Description |
|---|---|---|
--minCommits | 20 | Minimum number of instants to retain in the active timeline. Mirrors hoodie.keep.min.commits. |
--maxCommits | 30 | Maximum number of instants to retain in the active timeline. Mirrors hoodie.keep.max.commits. |
--commitsRetainedByCleaner | 10 | Number of commits to retain without cleaning. |
--enableMetadata | true | Whether the metadata table is enabled for this run. |
--sparkMemory | 1G | Spark executor memory. |
--sparkMaster | local | Spark master. |
The command reports Archival successfully triggered on a zero exit code from the Spark job, and
Failed to trigger archival otherwise. Check the Spark logs for why.
Compactions
To get an idea of the lag between compaction and writer applications, use the below command to list down all pending compactions.
hudi:trips->compactions show all

|==================================================================|
| <INSTANT_1> | REQUESTED| 35 |

To inspect a specific compaction plan, use
hudi:trips->compaction show --instant <INSTANT_1>
_________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Sometimes, it becomes necessary to remove a fileId from a compaction-plan inorder to speed-up or unblock compaction operation. Any new log-files that happened on this file after the compaction got scheduled will be safely renamed so that are preserved. Hudi provides the following CLI to support it
Unscheduling Compaction

No File renames needed to unschedule file from pending compaction. Operation successful.
In other cases, an entire compaction plan needs to be reverted. This is supported by the following CLI
hudi:trips->compaction unschedule --instant <compactionInstant>
.....
No File renames needed to unschedule pending compaction. Operation successful.
Repair Compaction
The above compaction unscheduling operations could sometimes fail partially (e:g -> DFS temporarily unavailable). With
partial failures, the compaction operation could become inconsistent with the state of file-slices. When you run
compaction validate, you can notice invalid compaction operations if there is one. In these cases, the repair
command comes to the rescue, it will rearrange the file-slices so that there is no loss and the file-slices are
consistent with the compaction plan
hudi:stock_ticks_mor->compaction repair --instant 20181005222611
......
Compaction successfully repaired

Savepoint and Restore
As the name suggest, "savepoint" saves the table as of the commit time, so that it lets you restore the table to this savepoint at a later point in time if need be. You can read more about savepoints and restore here
To trigger savepoint for a hudi table
connect --path /tmp/hudi_trips_cow/
commits show
set --conf SPARK_HOME=<SPARK_HOME>
savepoint create --commit 20220128160245447 --sparkMaster local[2]
To restore the table to one of the savepointed commit:
connect --path /tmp/hudi_trips_cow/
commits show
set --conf SPARK_HOME=<SPARK_HOME>
savepoints show
╔═══════════════════╗

╚═══════════════════╝
savepoint rollback --savepoint 20220128160245447 --sparkMaster local[2]
A rollback to a savepoint writes a restore instant on the timeline. Both show restores and show restore
expand a restore into one row per commit it reverted; show restore is the same view scoped to a single instant.
That is how you confirm after the fact what a restore actually undid. Note that --limit caps rows rather than
restores, so one restore that reverted a dozen commits fills the default page on its own.
hudi:trips->show restores --limit 10 --includeInflights false
hudi:trips->show restore --instant 20220128170512331
show restores accepts --limit (default 10), --sortBy (default unset), --desc (default false),
--headeronly (default false), and --includeInflights (default false, so only completed restores are listed).
show restore takes the instant to expand via --instant and the same --limit / --sortBy / --desc /
--headeronly display options; it has no --includeInflights.
Upgrade and Downgrade Table
In case the user needs to downgrade the version of Hudi library used, the Hudi table needs to be manually downgraded on the newer version of Hudi CLI before library downgrade. To downgrade a Hudi table through CLI, user needs to specify the target Hudi table version as follows:
connect --path <table_path>
downgrade table --toVersion <target_version>
The following table shows the Hudi table versions corresponding to the Hudi release versions:
| Hudi Table Version | Hudi Release Version(s) |
|---|---|
NINE or 9 | 1.1.x - 1.2.x |
EIGHT or 8 | 1.0.x |
SIX or 6 | 0.14.x - 0.15.x |
FIVE or 5 | 0.12.x - 0.13.x |
FOUR or 4 | 0.11.x |
THREE or 3 | 0.10.x |
TWO or 2 | 0.9.x |
ONE or 1 | 0.6.x - 0.8.x |
ZERO or 0 | 0.5.x and below |
For example, to downgrade a table from version EIGHT(8) (current version) to SIX(6), you should run (use proper Spark master based
on your environment)
downgrade table --toVersion SIX --sparkMaster local[2]
or
downgrade table --toVersion 6 --sparkMaster local[2]
You can verify the table version by looking at the hoodie.table.version property in .hoodie/hoodie.properties under
the table path:
hoodie.table.version=6
Hudi CLI also provides the ability to manually upgrade a Hudi table. To upgrade a Hudi table through CLI:
upgrade table --toVersion <target_version>
Table upgrade is automatically handled by the Hudi write client in different deployment modes such as Hudi Streamer
after upgrading the Hudi library so that the user does not have to do manual upgrade. Such automatic table upgrade
is the recommended way in general, instead of using upgrade CLI command.
Table upgrade from table version ONE to TWO requires key generator related configs such as "hoodie.datasource.write.recordkey.field", which is only available when user configures the write job. So the table upgrade from version ONE to TWO through CLI is not supported, and user should rely on the automatic upgrade in the write client instead.
You may also run the upgrade command without specifying the target version. In such a case, the latest table version corresponding to the library release version is used:
upgrade table
Record Index Lookup
To look up a record's file location via the Record Level Index (RLI) stored in the Metadata Table:
hudi:trips->metadata lookup-record-index --record_key <key>
For a partitioned (non-global) RLI, the partition path is required:
hudi:trips->metadata lookup-record-index --record_key <key> --partition_path <partition>
The --partition_path argument is optional for a global RLI (where record keys are unique across all partitions) and required for a partitioned RLI. If --partition_path is omitted for a partitioned RLI, the command will return an error. The output columns are Record key, Partition path, File Id, and Instant time.
To drop the record index partition from the Metadata Table entirely, for example before rebuilding it. Note the
prerequisite: unlike metadata delete, this command runs on a Spark engine context, and that context is only
created by metadata create, metadata init or metadata list-partitions. Run one of those first in the same
session, otherwise the command fails on an uninitialised Spark context rather than doing anything:
hudi:trips->metadata list-partitions --sparkMaster local[2]
hudi:trips->metadata delete-record-index --backup true
Record Index has been deleted from the Metadata Table and backed up to /user/hive/warehouse/table1/.hoodie/.metadata_record_index_20260831090412345
--backup defaults to true. The backup is a rename rather than a copy, so it is cheap: the
.hoodie/metadata/record_index partition is moved to .hoodie/.metadata_record_index_<instantTime>, where
<instantTime> is the current instant in yyyyMMddHHmmssSSS form. Pass --backup false to delete the partition
outright, in which case the output is just Record Index has been deleted from the Metadata Table and the only way
back is to rebuild the index.
Either way the command first flips the partition off in the table config, so readers stop consulting the index before
the files go away. If the record index partition does not exist, or if the backup rename fails, the message still
prints with null in place of the backup path, so a null there is not by itself confirmation that the partition was
absent.
Change Hudi Table Type
There are cases we want to change the hudi table type. For example, change COW table to MOR for more efficient and lower latency ingestion; change MOR to COW for better read performance and compatibility with downstream engines. So we offer the table command to perform this modification conveniently.
Changing COW to MOR, we can simply modify the hoodie.table.type in hoodie.properties to MERGE_ON_READ.
While changing MOR to COW, we must make sure all the log files are compacted before modifying the table type, or it will cause data loss.
connect --path <table_path>
table change-table-type <target_table_type>
The parameter target_table_type candidates are below:
| target table type | comment |
|---|---|
| MOR | Change COW table to MERGE_ON_READ. |
| COW | Change MOR table to COPY_ON_WRITE. By default, changing to COW will execute all pending compactions and perform a full compaction if any log file left. Set --enable-compaction=false will disable the default compaction. There are params can be set for the compaction operation: --parallelism: Default 3. Parallelism for hoodie compaction--sparkMaster: Default local. Spark Master--sparkMemory: Default 4G. Spark executor memory--retry: Default 1. Number of retries--propsFilePath: Default . path to properties file on localfs or dfs with configurations for hoodie client for compacting--hoodieConfigs: Default . Any configuration that can be set in the properties file can be passed here in the form of an array |
Example below is changing MOR table to COW:
connect --path /var/dataset/test_table_mor2cow

Changing the Meta Fields Mode
hoodie.meta.fields.mode decides which of Hudi's meta columns are physically written into base files. It is a
storage-layout decision baked in at write time, so a write can never change it on an existing table.
table set-meta-fields-mode is the sanctioned way to change it.
hudi:trips->table set-meta-fields-mode --target-mode COMMIT_TIME_ONLY
--target-mode accepts ALL, NONE, COMMIT_TIME_ONLY, FILE_NAME_ONLY or COMMIT_TIME_AND_FILE_NAME. The value
is resolved case-insensitively and trimmed, so commit_time_only is accepted too. Setting the mode the table is
already in is a no-op and reports as much.
On a table that already has commits, two guards apply, because this command changes the table property without rewriting a single existing file:
- Widening is refused outright, and
--forcedoes not override it. Widening means the target mode populates a meta column the current mode does not. Since earlier files are not rewritten, the table would advertise a column that is null for every row written so far, and incremental queries and file-name lookups silently skip exactly those rows. To widen, recreate the table. The comparison the CLI makes isMetaFieldsMode#isWiderThan, the same helper the write path uses. Note the write path itself is stricter rather than equivalent: it rejects any writer mode that differs from the table's, and consultsisWiderThanonly to choose the error wording. - Narrowing needs
--force(defaultfalse). It leaves mixed-mode files: old commits keep the old layout, new commits use the new one, and incremental and file-pruning semantics differ between the two sets. Passing--forcelogs a warning recording the transition and the commit count.
Neither guard applies to a table with no commits, where the mode can be set freely.
Inspecting the Timeline
commits show lists completed commits, and only commit, deltacommit, replacecommit and clustering actions. The
timeline commands show every instant regardless of action and state, which is what you want when diagnosing a stuck
table: a compaction sitting in REQUESTED never appears in commits show, and neither does a rollback, in any
state.
hudi:trips->timeline show active --limit 10
hudi:trips->timeline show incomplete
Both print Instant, Action, State, and the Requested / Inflight / Completed file modification times.
timeline show incomplete restricts the listing to instants that are not yet completed.
| Option | Default | Applies to | Description |
|---|---|---|---|
--limit | 10 | both | Number of rows to display. |
--sortBy | unset | both | Field to sort by. |
--desc | false | both | Reverse the ordering. |
--headeronly | false | both | Print the header only. |
--show-rollback-info | false | both | Annotate the Action column in both directions: Rolls back ... on a rollback instant, and Rolled back by ... on any instant a rollback targeted. |
--show-time-seconds | false | both | Include seconds in the instant file modification times. |
--with-metadata-table | false | timeline show active only | Show the metadata table timeline alongside the data table, adding MT Action, MT State and the three matching MT time columns. |
The metadata table has its own timeline, and the two can disagree when a metadata commit fails. To read it directly:
hudi:trips->metadata timeline show active --limit 10
hudi:trips->metadata timeline show incomplete
These accept --limit, --sortBy, --desc, --headeronly and --show-time-seconds. They have no
--show-rollback-info and no --with-metadata-table, since they are already scoped to the metadata table.
Diffing a File or Partition
diff file and diff partition replay the timeline and show every commit that touched a given file group or
partition, which is the quickest way to answer "what has been writing to this file". Both report the standard commit
columns plus the write statistics for the matching entries only.
hudi:trips->diff file --fileId 5f8a1e0b-1b4b-4a3f-9b1a-2c7d6e5f4a3b-0 --limit 10
hudi:trips->diff partition --partitionPath 2026/08/26 --includeArchivedTimeline true
diff file takes --fileId and diff partition takes --partitionPath as a partition path relative to the table
base path. diff partition is only meaningful on a partitioned table. Both then share these options:
| Option | Default | Description |
|---|---|---|
--includeArchivedTimeline | false | Also scan archived instants, not just the active timeline. |
--startTs | unset, meaning now minus 10 days | Start of the instant range. Only applied when --includeArchivedTimeline is true. |
--endTs | unset, meaning now minus 1 day | End of the instant range. Only applied when --includeArchivedTimeline is true. |
--limit | -1, meaning no limit | Number of rows to display. |
--sortBy | unset | Field to sort by. |
--desc | false | Reverse the ordering. |
--headeronly | false | Print the header only. |
Note the interaction between the three range options, which is easy to get wrong. --startTs and --endTs are used
to select archived instants only. With the default --includeArchivedTimeline false the whole active timeline is
scanned and both bounds are ignored, so passing a narrow range does not restrict the output. Set
--includeArchivedTimeline true for the bounds to take effect, and note that the archived range is then merged with
the full active timeline rather than replacing it.
Repairing a Table
repair show empty commit metadata scans completed instants on the active timeline and reports the ones whose
metadata file is empty, which is what a commit interrupted between file creation and metadata write leaves behind.
hudi:trips->repair show empty commit metadata
Note that this command writes its findings to the CLI log at WARN level rather than returning a table, so with the
default logging configuration you will see the Empty Commit: ... lines in the console log rather than in a rendered
result. It only reports; it does not modify the timeline.
rename partition rewrites the data under one partition value into another, as a Spark job, and deletes the old
partition on success. It only works on a table with a single partition field: the rewrite looks the partition field
up by name in the dataframe schema, and on a multi-field table that name is the comma-joined list, so the job fails
before writing anything.
hudi:trips->set --conf SPARK_HOME=<SPARK_HOME>
hudi:trips->rename partition --oldPartition 2026/08/26 --newPartition 2026-08-26 --sparkMaster local[2]
repair deprecated partition is the special case of that rename for tables written before Hudi settled on its
placeholder for the null partition value: it rewrites data from the deprecated default partition into
__HIVE_DEFAULT_PARTITION__.
hudi:trips->repair deprecated partition --sparkMaster local[2]
Both take --sparkProperties (a Spark properties file path, empty by default), --sparkMaster (unset by default,
which means yarn -- see the note under the Command reference legend) and
--sparkMemory (4G by default). Both read the old partition, rewrite those records under the new partition value,
and then issue a delete_partition write against the old one, so the change goes through the timeline rather than
behind it. Both are a no-op when the old partition holds no records.
They differ in one respect worth knowing: rename partition additionally removes the old partition directory from
storage after the delete write, logging a warning if that removal fails, whereas repair deprecated partition leaves
the emptied default directory in place. Either way these rewrite data, so take a savepoint first if the table
matters.
Auditing Storage Locks
When a table uses a storage-based lock provider, the lock provider can record every lock transition to a set of JSONL
files, so that a suspected concurrency violation can be reconstructed after the fact. The audit is off by default and
is controlled by a config file next to the locks themselves, at
<basePath>/.hoodie/.locks/audit_enabled.json; the audit records land in <basePath>/.hoodie/.locks/audit/.
hudi:trips->locks audit enable
Lock audit enabled successfully.
Audit config written to: /user/hive/warehouse/table1/.hoodie/.locks/audit_enabled.json
Audit files will be stored at: /user/hive/warehouse/table1/.hoodie/.locks/audit
locks audit status reports whether auditing is on, and where both the config and the records live. A table that has
never had auditing enabled reports DISABLED with the config file marked (not found).
hudi:trips->locks audit status
Lock Audit Status: ENABLED
Table: /user/hive/warehouse/table1
Config file: /user/hive/warehouse/table1/.hoodie/.locks/audit_enabled.json
Audit files location: /user/hive/warehouse/table1/.hoodie/.locks/audit
locks audit validate is the reason to collect the records. It parses every .jsonl file in the audit folder into
transaction windows and checks them against each other. Overlapping windows are reported as errors, since two writers
holding the lock at once is exactly the violation the lock provider exists to prevent. A transaction that never
released its lock is reported as a warning, which usually means a driver OOM or a non-graceful shutdown rather than a
correctness problem. The verdict is PASSED, WARNING when only warnings were found, or FAILED when any error was.
hudi:trips->locks audit validate
Validation Result: PASSED
Audit Files: 12 total, 12 parsed successfully, 0 failed to parse
Transactions Validated: 12
Issues Found: 0
Details: All audit lock transactions validated successfully
With no audit folder or no audit files the command reports PASSED with zero transactions validated, so a PASSED
verdict on its own does not prove that auditing was ever on. Check locks audit status first.
locks audit cleanup prunes old records. --ageDays defaults to 7 and --dryRun defaults to false, so run it
with --dryRun true first to see what it would remove.
hudi:trips->locks audit cleanup --dryRun true --ageDays 30
locks audit disable turns auditing off. It keeps the existing records by default; pass --keepAuditFiles false to
delete them at the same time, which internally runs the same cleanup with no age threshold.
hudi:trips->locks audit disable --keepAuditFiles true
All five commands require a table to be connected, and report No Hudi table loaded. Please connect to a table first.
otherwise.
Command reference
Every command hudi-cli exposes, grouped by area, with its options and their defaults. An option marked
(required) has no default and must be supplied; a value in backticks after an option is its default; an option
listed with neither is optional and unset by default, which for most commands means the empty string reaches the
command. The sections above cover the commonly used ones in more depth.
One default is worth stating up front because it is not the empty string it looks like: an unset or blank
--sparkMaster resolves to yarn. The CLI treats a blank value as absent and falls back to its own default, so
every --sparkMaster shown below without a value runs against YARN unless you pass something. The compaction
commands are the exception: they declare local explicitly. Note marker delete is not an exception despite
looking like one, since it declares no default and so resolves to yarn like the rest.
Some entries are aliases of the same command rather than distinct ones. refresh, metadata refresh,
commits refresh, cleans refresh and savepoints refresh are five names for one method that reloads the table
metadata, and temp query / temp_query, temp delete / temp_delete and temps show / temps_show are
underscore and space spellings of the same three commands.
