few comments.

1. 

{code}     
     if (application.isAppInCompletedStates()) {              
          RMAuditLogger.logSuccess(callerUGI.getShortUserName(),
                  AuditConstants.FAIL_ATTEMPT_REQUEST, "ClientRMService"
                  applicationId);
              return response;
  }     
{code}

For {{failApplicationAttempt}}, this is not correct. We want to send normal 
response only for those apps whihc are in final states. But if app is in 
NEW_SAVING etc, we must throw exception. That is missed now.

2. {{updateApplicationTimeouts}} has some unwanted code. Pls remove it.
{code}
1634        if (application.isAppInCompletedStates()) {
1635    
1636        }
{code}
