Back up the Ranger configuration

You must backup the Ranger configuration.

After the upgrade, in case of SSL enabled environment, keystore & truststore configurations used by Ranger tagsync, usersync & plugins must be verifiied to ensure proper communication to Ranger Admin.

In case of errors, keystore must be recreated and corresponding configurations in Ambari updated. The example for tagsync and the command used to create the keystore for tagsync is: keytool -genkey -keyalg RSA -alias rangertagsync -keystore rangertagsynckeystore.jks -storepass xasecure -validity 360 -keysize 2048.

After keystore is updated, update the tagsync properties (in the Advanced ranger-tagsync-policymgr-ssl section) xasecure.policymgr.clientssl.keystore with correct value and set the password.
