Cloud storage

The options on the "Cloud Storage" page allow you to optionally specify the base storage location used for YARN and Zeppelin.

During environment creation under Data Access > Storage Location Base you configure a default S3ADLS Gen2 base storage location for the environment, and all Data Hub clusters created within that environment use this location. The Cloud Storage options in the Data Hub cluster wizard allow you to additionally specify a different location for YARN application logs and Zeppelin Notebook's root directory:
  • Existing Base Storage Location - By default, this is set to the Storage Location Base configured on environment level. If you do not want to make any changes, simply leave this blank. If you would like to use a different location for YARN application logs and Zeppelin Notebook's root directory, you can specify a different S3ADLS Gen2 location. Note that the specified S3ADLS Gen2 location must exist prior to Data Hub cluster creation and that you must adjust the IAM policies created during environment's cloud storage setup to make sure that IDBroker has write access to this location.
  • Path for YARN Application Logs property - This directory structure gets created automatically during cluster creation. You can customize it if you would like it be different than what is suggested by default.
  • Path for Zeppelin Notebooks Root Directory property - This directory structure gets created automatically during cluster creation. You can customize it if you would like it to be different than what is suggested by default.
