Subject [jira] [Updated] (YARN-7017) Enable preemption for a single queue.
Date Tue, 15 Aug 2017 19:03:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-7017?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

sarun updated YARN-7017:
------------------------
    Description: 
*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.
