MR-279: port MAPREDUCE-2324 to mrv2
-----------------------------------

                 Key: MAPREDUCE-2723
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2723
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
          Components: mrv2
    Affects Versions: 0.23.0
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans
             Fix For: 0.23.0


MRV2 currently does not take reduce disk usage into account when trying to schedule a container.
 For feature parity with the original map reduce it should be extended to allow for disk space
requests within containers along with RAM requests.  We then also need to port MAPREDUCE-2324
to the scheduler to allow it to avoid starvation of containers that might never get the resources
that they need.
