Limitations

Review the following limitations before you deploy the HBase plug-in:

  • Only RHEL and SUSE platforms are supported for HBase clusters and backup hosts.

  • HBase 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 a highly available HBase cluster, if a failover happens during a backup or restore operation, the job fails.

  • You can cancel a backup and restore job manually while the discovery job for a backup operation is in progress. However, in this case the snapshot entry does not get removed from the HBase web graphical user interface (GUI).

  • Backup of read-only tables is not supported.

  • You need to add tables one-by-one in the backup selection when you create the backup policy.

  • 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.

  • 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.
