Starting JobTracker with a wrong keytab should throw error right away
---------------------------------------------------------------------
Key: MAPREDUCE-1630
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1630
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Arun Ramani
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.
