Subject [jira] [Commented] (YARN-1471) The SLS simulator is not running the preemption policy for CapacityScheduler
Date Fri, 02 Jun 2017 23:04:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-1471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16035595#comment-16035595

Konstantin Shvachko commented on YARN-1471:
-------------------------------------------

I see a new patch in YARN-6608. So this is progressing. And if this change is incorporated
there we just need to port into branch-2.7. Will do just that if there are no objections.

> The simulator does not run the ProportionalCapacityPreemptionPolicy monitor.  This is
because the policy needs to interact with a CapacityScheduler, and the wrapping done by the
simulator breaks this.
