["Arpit Agarwal (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HDFS-8831?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Arpit Agarwal updated HDFS-8831:
--------------------------------
    Release Note: Add Trash support for deleting files within encryption zones. Deleted files will remain encrypted and they will be moved to a “.Trash” subdirectory under the root of the encryption zone, prefixed by $USER/current. Checkpoint and expunge continue to work like the existing Trash.  (was: Trash is now supported for deletion of files within encryption zone after HDFS-8831. The deleted encrypted files will remain encrypted and be moved to .Trash subdirectory under the root of the encryption zone prefixed by $USER/current with checkpoint and expunge working similar to existing Trash.)

> Currently, "Soft Delete" is only supported if the whole encryption zone is deleted. If you delete files whinin the zone with trash feature enabled, you will get error similar to the following 
> {code}
> rm: Failed to move to trash: hdfs://HW11217.local:9000/z1_1/startnn.sh: /z1_1/startnn.sh can't be moved from an encryption zone.
> {code}
> This JIRA is proposed to support trash for deletion of files within encryption zone.
