Enabling and disabling HDFS snapshots

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.

Minimum required role: Cluster Administrator or Full Administrator.

Go to the Cloudera Manager > HDFS service > File Browser tab.
Go to the directory you want to enable for snapshots.
Click the drop-down menu next to the full file path and select Enable Snapshots.

note
Once you enable snapshots for a directory, you cannot enable snapshots on any of its subdirectories. Snapshots can be taken only on directories that have snapshots enabled.
Click Disable Snapshots to disable snapshots for a directory that has snapshots enabled.

important
If snapshots of the directory exist, they must be deleted before snapshots can be disabled.
