[jira] [Created] (YARN-3769) Preemption occurring unnecessarily because preemption doesn't consider user limit

Eric Payne created YARN-3769:
--------------------------------

             Summary: Preemption occurring unnecessarily because preemption doesn't consider user limit
                 Key: YARN-3769
                 URL: https://issues.apache.org/jira/browse/YARN-3769
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacityscheduler
    Affects Versions: 2.7.0, 2.6.0, 2.8.0
            Reporter: Eric Payne
            Assignee: Eric Payne


We are seeing the preemption monitor preempting containers from queue A and then seeing the capacity scheduler giving them immediately back to queue A. This happens quite often and causes a lot of churn.
