   what exception was thrown here that caused the problem?  Description should 
state.  
   
   This was likely in this order because if you don't unregister with YARN it 
could retry the application, if the staging directory is gone, that retry will 
now fail since application jar not there. Since the unregistered failed its 
possible YARN doesn't know it succeeded so then it could retry and all you 
could see if missing staging directory and you have to go searching for the 
real error.
   
   I don't see reproduce case or a test here so it would be nice to test this 
to see what actually happens.
