             Summary: Preemption happening on non-preemptable queues
                 Key: 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.
