[jira] Created: (MAPREDUCE-944) Extend FairShare scheduler to fair-share memory usage in the cluster

Extend FairShare scheduler to fair-share memory usage in the cluster
--------------------------------------------------------------------

                 Key: MAPREDUCE-944
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-944
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: contrib/fair-share
            Reporter: dhruba borthakur


The FairShare Scheduler has an extensible LoadManager API to regulate allocating new tasks on a particular TaskTracker. In similar lines, it would be nice if the FairShare Scheduler can have a pluggable policy to regulate new tasks from a particular job. This will allow one to skip scheduling tasks of a job that  is eating a large percentage of memory in the cluster, i.e. fair-share of memory resources among jobs.
