Supported Storage System

There are two storage systems support Hudi .

  • Azure Blob Storage
  • Azure Data Lake Gen 2

Verified Combination of Spark and storage system

HDInsight Spark2.4 on Azure Data Lake Storage Gen 2

This combination works out of the box. No extra config needed.

Databricks Spark2.4 on Azure Data Lake Storage Gen 2

  • Import Hudi jar to databricks workspace

  • Mount the file system to dbutils.
    dbutils.fs.mount(
      source = "abfss://xxx@xxx.dfs.core.windows.net",
      mountPoint = "/mountpoint",
      extraConfigs = configs)
    
  • When writing Hudi dataset, use abfss URL
    inputDF.write
      .format("org.apache.hudi")
      .options(opts)
      .mode(SaveMode.Append)
      .save("abfss://<<storage-account>>.dfs.core.windows.net/hudi-tables/customer")
    
  • When reading Hudi dataset, use the mounting point
    spark.read
      .format("org.apache.hudi")
      .load("/mountpoint/hudi-tables/customer")
