[jira] [Created] (MAPREDUCE-4327) Enhance CS to schedule accounting for both memory and cpu cores

Arun C Murthy created MAPREDUCE-4327:
----------------------------------------

             Summary: Enhance CS to schedule accounting for both memory and cpu cores
                 Key: MAPREDUCE-4327
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4327
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: mrv2, resourcemanager, scheduler
    Affects Versions: 2.0.0-alpha
            Reporter: Arun C Murthy
            Assignee: Arun C Murthy


With YARN being a general purpose system, it would be useful for several applications (MPI et al) to specify not just memory but also CPU (cores) for their resource requirements. Thus, it would be useful to the CapacityScheduler to account for both.
