Pre-Upgrade Steps for HBase Client

Complete the following steps before you upgrade HBase Client with or without the MapR Installer.

About this task

If you made configuration changes that you want to carry over to the next version of HBase Client, you need to back up configuration files.

Procedure

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 Client by merging the configuration files back into /opt/mapr/hbase/hbase-<version>/conf/. See Post-Upgrade Steps for HBase Client for more information.
