[jira] [Created] (YARN-685) Capacity Scheduler is not distributing the reducers tasks across the cluster

Devaraj K created YARN-685:
------------------------------

             Summary: Capacity Scheduler is not distributing the reducers tasks across the cluster
                 Key: YARN-685
                 URL: https://issues.apache.org/jira/browse/YARN-685
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacityscheduler
    Affects Versions: 2.0.4-alpha
            Reporter: Devaraj K


If we have reducers whose total memory required to complete is less than the total cluster memory, it is not assigning the reducers to all the nodes uniformly(~uniformly). Also at that time there are no other jobs or job tasks running in the cluster.
