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 (also provided by Full Administrator)
Enabling an HDFS Directory for Snapshots
- From the Clusters tab, select the CDH HDFS service.
- 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.
Disabling a Snapshottable Directory
To disable snapshots for a directory that has snapshots enabled, use 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.
