Sandy Ryza resolved MAPREDUCE-3946.
-----------------------------------
Resolution: Duplicate
> If a resource requirement is higher than available on any node, job should
> fail early
> -------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-3946
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3946
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 0.24.0, 0.23.2
> Reporter: Todd Lipcon
>
> If you configure the NMs to have 1GB of RAM each, and then try to submit a
> job which has an AM resource requirement of 1.5GB, the job will neither run
> nor fail. Instead, it will slowly sop of all of the resources in the cluster
> as "reservations" despite the fact that it will never be able to schedule
> something. Instead, it should fail early indicating that the required memory
> allocation is infeasible.
