Provide option to fail jobs when submitted to non-existent pools.
-----------------------------------------------------------------

                 Key: MAPREDUCE-2836
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2836
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: contrib/fair-share
            Reporter: Jeff Bean


In some environments, it might be desirable to explicitly specify the fair scheduler pools
and to explicitly fail jobs that are not submitted to any of the pools. 

Current behavior of the fair scheduler is to submit jobs to a default pool if a pool name
isn't specified or to create a pool with the new name if the pool name doesn't already exist.
There should be a configuration option for the fair scheduler that causes it to noisily fail
the job if it's submitted to a pool that isn't pre-specified or if the specified pool doesn't
exist.
