Pre-Upgrade Steps for HBase

You need to take a snapshot and back up configuration properties files if you made changes to properties that you want to carry over to the next version.

  1. Take a snapshot of the hbase volume.
    The snapshot creates a backup of the volume data that you can use to recover your data in the event that corruption occurs during the upgrade process.
  2. Copy the configuration files in /opt/mapr/hbase/hbase-<version>/conf/ to a location outside the MapR installation directory.
    After upgrading, you can reapply changes to the updated HBase installation using the backup.
