Ambari Properties backup

You must make a safe copy of the Ambari Server configuration file found at /etc/ambari-server/conf/ambari.properties.

During the Ambari upgrade, the existing /var/lib/ambari-server/ambari-env.sh file is overwritten and a backup copy of ambari-env.sh (with extension .rpmsave) is created. If you have manually modified ambari-env.sh (for example, to change Ambari Server heap), you must reapply your changes in the new file.

To purge your Ambari cluster, see Purging Ambari Server Database History.
