Subject [jira] [Created] (YARN-3924) Submitting an application to standby ResourceManager should respond better than Connection Refused

Dustin Cote created YARN-3924:
---------------------------------

             Summary: Submitting an application to standby ResourceManager should respond
better than Connection Refused
                 Key: YARN-3924
                 URL: https://issues.apache.org/jira/browse/YARN-3924
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: resourcemanager
            Reporter: Dustin Cote
            Priority: Minor


When submitting an application directly to a standby resource manager, the resource manager
responds with 'Connection Refused' rather than indicating that it is a standby resource manager.
 Because the resource manager is aware of its own state, I feel like we can have the 8032
port open for standby resource managers and reject the request with something like 'Cannot
process application submission from this standby resource manager'.  

This would be especially helpful for debugging oozie problems when users put in the wrong
address for the 'jobtracker' (i.e. they don't put the logical RM address but rather point
to a specific resource manager).
