> If the JobTracker is started with a wrong key tab file, it should die 
> immediately throwing the right error to the user. Right now, the JobTracker 
> keeps trying to login with the available credentials and hence the process 
> does not die immediately. So, to the user it appears like the JobTracker 
> process is running successfully. This is misleading.
