Limitations
Review the following limitations before you deploy the NetBackup for Hadoop plug-in:
Only RHEL and SUSE platforms are supported for backup hosts. For platforms supported for Hadoop clusters, see the NetBackup Database and Application Agent Compatibility List.
Delegation Token authentication method is not supported for NetBackup 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 NetBackup for 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.
Backup and restore operations are not supported with Kerberos authentication if NB_FIPS_MODE is enabled at the
bp.conf
.Note:
To perform backup with Kerberos authentication, deploy a new backup host with NB_FIPS_MODE=0 or disabled.
