Procedure

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.
-
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.
