The final step in the Ranger upgrade process requires you to re-enable the Ranger plugins. Although you are only required to enable HDFS in your cluster, you should re-enable all of the Ranger plugins because class names have changed for the 2.3.6 release, and to ensure smooth operation of Ranger services in your cluster.

	Note
	When you enable each Ranger plugin, be sure to remove all 2.2 class name values.

	Note
	Re-enabling a Ranger plugin does not affect policies you have already created. As long as you use the same database as the Policy store, all of your data will remain intact.

To re-enable the Ranger plugins, use the links listed below to access instructions in the Non-Ambari Cluster Installation guide that describe editing the install.properties file and enabling the Ranger plugins:

	Important
	Before enabling the HDFS plugin, remove set-hdfs-plugin-env.sh from /etc/hadoop/conf. You will need to re-enable this plugin after the upgrade is complete.
