Validate the Jobs Output Specification as the first statement in JobSubmitter.submitJobInternal(Job,
Cluster) method
--------------------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-3154
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3154
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: client, mrv2
    Affects Versions: 0.23.0, 0.24.0
         Environment: mrv2
            Reporter: Abhijit Suresh Shingate
            Assignee: Abhijit Suresh Shingate


Presently the output specification is validated after getting new JobId from ClientRMService,
Copying the job jar, Configuration file, archives etc.

Instead of that move following Job Output specification validation call to the begining of
JobSubmitter.submitJobInternal(Job, Cluster) method.

{code}
checkSpecs(job);
{code}

This will avoid unnecessary work in case of invalid output specs.
