Subject [jira] [Created] (YARN-7017) Enable preemption for a single queue.
Date Tue, 15 Aug 2017 18:59:02 GMT
sarun created YARN-7017:
---------------------------

             Summary: Enable preemption for a single queue.
                 Key: YARN-7017
                 URL: https://issues.apache.org/jira/browse/YARN-7017
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: yarn
            Reporter: sarun


PROBLEM
How to enable preemption on a single queue in a cluster?
DESCRIPTION
As of today the only way to enable preemption at a queue level is:
* Enable cluster level preemption
* Disable preemption on the queues where not required using yarn.scheduler.capacity.<queue-path>.disable_preemption
to true

Can we have some sort of a parameter like 
*_yarn.scheduler.capacity.<queue-path>.enable_preemption_*
which would just enable preemption per queue instead of going the other way round which is
more time consuming and error prone.
