> 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.
