The fix deployed for SPARK-21541 resulted in the Application Master to set the final status of a spark application as Failed for the client mode as the flag 'registered' was not being set to true for client mode. So, in order to fix the issue, I have set the flag 'registered' as true in client mode on successfully registering Application Master.
