Limitations
Review the following limitations before you deploy the Hadoop plug-in:
Only RHEL and SUSE platforms are supported for Hadoop clusters and backup hosts.
Delegation Token authentication method is not supported for Hadoop clusters.
Hadoop plug-in does not capture Extended Attributes (xattrs) or Access Control Lists (ACLs) of an object during backup and hence these are not set on the restored files or folders.
For highly available Hadoop cluster, if fail-over happens during a backup or restore operation, the job fails.
If you cancel a backup job manually while the discovery job for a backup operation is in progress, the snapshot entry does not get removed from the Hadoop web graphical user interface (GUI).
If the CRL expires during the backup of an HTTPS-based Hadoop cluster, the backup runs partially.
If you have multiple CRL-based Hadoop clusters, ensure that you add different backup hosts for every cluster.
