             Summary: Add cross-user preemption within CapacityScheduler's 
leaf-queue
                 Key: YARN-2069
                 URL: https://issues.apache.org/jira/browse/YARN-2069
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: capacityscheduler
            Reporter: Vinod Kumar Vavilapalli
            Assignee: Vinod Kumar Vavilapalli


Preemption today only works across queues and moves around resources across 
queues per demand and usage. We should also have user-level preemption within a 
queue, to balance capacity across users in a predictable manner.
