exception to avoid thread from getting killed on yarn restart.

SPARK-5613: Catch the ApplicationNotFoundException exception to avoid thread from getting killed on yarn restart.
[SPARK-5613] Added a catch block to catch the ApplicationNotFoundException. Without this catch block the thread gets killed on occurrence of this exception. This Exception occurs when yarn restarts and tries to find an application id for a spark job which got interrupted due to yarn getting stopped.
See the stacktrace in the bug for more details.
