Subject [jira] [Created] (YARN-3275) Preemption happening on non-preemptable queues
Date Fri, 27 Feb 2015 16:45:04 GMT
Eric Payne created YARN-3275:
--------------------------------

             Summary: Preemption happening on non-preemptable queues
                 Key: YARN-3275
                 URL: https://issues.apache.org/jira/browse/YARN-3275
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.7.0
            Reporter: Eric Payne
            Assignee: Eric Payne


YARN-2056 introduced the ability to turn preemption on and off at the queue level. In cases
where a queue goes over its absolute max capacity (YARN:3243, for example), containers can
be preempted from that queue, even though the queue is marked as non-preemptable.

We are using this feature in large, busy clusters and seeing this behavior.
