For snapshots to be created, HDFS directories must be enabled for snapshots. You cannot
specify a directory as part of a snapshot policy unless it has been enabled for
snapshots.
To enable an HDFS directory for snapshots, select your cluster HDFS service on the
Clusters tab.
Go to the File Browser tab.
Go to the directory you want to enable for snapshots.
In the File Browser, click the drop-down menu next to the full file path and select
Enable Snapshots.
To disable snapshots for a directory that has snapshots enabled, click Disable
Snapshots from the drop-down menu button at the upper right. If snapshots of
the directory exist, they must be deleted before snapshots can be disabled.
