Backing up a HBase cluster

You can either schedule a backup job or run a backup job manually. See, NetBackup Administrator's Guide, Volume I

For overview of the backup process, See Backing up HBase data.

The backup process comprises of the following stages:

  1. Pre-processing: In the pre-processing stage, the first backup host that you have configured with the BigData policy, triggers the discovery. At this stage, a snapshot of the complete backup selection is generated. The snapshot details are visible on the Region server web interface.

  2. Data transfer: During the data transfer process, one child job is created for each backup host.

  3. Post-processing: As part of the post-processing, NetBackup cleans up the snapshots on Region server.

Considerations

  • On the Hmaster, set the PasswordAuthentication field to Yes in the /etc/ssh/sshd_config file. After you update the file, restart sshd.

    Ensure that all the cluster servers support supports same Hash Key algorithm ( RSA)

  • Snapshots are not cleaned up if you cancel a job manually. After cancelling the job you must manually delete snapshots from the HBase shell.

  • If you take backup of an empty table, you need to clean the snapshot manually from the HBase shell.

  • See Best practices for backing up a HBase cluster.
