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.
