>   Original Estimate: 1h
>  Remaining Estimate: 1h

> 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.
