             Summary: client lacks delegation token exception details when 
application submit fails
                 Key: YARN-2147
                 URL: https://issues.apache.org/jira/browse/YARN-2147
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.4.0
            Reporter: Jason Lowe
            Priority: Minor


When an client submits an application and the delegation token process fails 
the client can lack critical details needed to understand the nature of the 
error.  Only the message of the error exception is conveyed to the client, 
which sometimes isn't enough to debug.
