Description

During an Express Upgrade from HDP 2.6.5 -> HDP 3.0.1.0, Stopping/Starting Ranger failed, as we had accidentally missed updating the password to conform to the new rules ("Password should be minimum 8 characters with minimum one alphabet and one numeric").

However, although Starting Ranger from a Stopped state correctly failed, Restarting Ranger from a Stopped state incorrectly appeared to complete successfully, and the service remained up/green in Ambari. In reality, the service was not listening on the relevant port and was not actually functioning.

After fixing the password, both Stopping/Starting and Stopping/Restarting the service genuinely succeeded.
