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.
