> 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.
