GCS Filesystem

For Hudi storage on GCS, regional buckets provide an DFS API with strong consistency.

GCS Configs

There are two configurations required for Hudi GCS compatibility:

• Adding GCS Credentials for Hudi
• Adding required jars to classpath

GCS Credentials

Add the required configs in your core-site.xml from where Hudi can fetch them. Replace the fs.defaultFS with your GCS bucket name and Hudi should be able to read/write from the bucket.
