Subject [jira] [Commented] (YARN-2056) Disable preemption at Queue level
Date Thu, 21 Aug 2014 01:45:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-2056?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14104931#comment-14104931

Wangda Tan commented on YARN-2056:

May a another way to do this is add a config in per queue, like {{..queue-path.disable_preemption}}.
And in {{ProportionalCapacityPreemptionPolicy#cloneQueues}}, if a queue's used capacity more
than guaranteed resource, and it set disable preemption. We will not create a TempQueue for
We will not require RM restart if queue property changed (queue property will be refreshed
and PreemptionPolicy will get such changes.

Does it make sense?
