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.
