Subject [jira] [Commented] (YARN-2009) Priority support for preemption in ProportionalCapacityPreemptionPolicy
Date Fri, 14 Oct 2016 22:31:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-2009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15576735#comment-15576735

Eric Payne commented on YARN-2009:
----------------------------------

Hi [~sunilg]. I think I would suggest to do the following:
{code:title=current FifoIntraQueuePreemptionPlugin#calculateToBePreemptedResourcePerApp}
      Resources.subtractFrom(preemtableFromApp, tmpApp.getAMUsed());
{code}

{code:title=suggested FifoIntraQueuePreemptionPlugin#calculateToBePreemptedResourcePerApp}
      if (Resources.lessThan(rc, clusterResource,
            Resources.subtract(tmpApp.getUsed(), preemtableFromApp),
            tmpApp.getAMUsed())) {
        Resources.subtractFrom(preemtableFromApp, tmpApp.getAMUsed());
      }
{code}

> While preempting containers based on the queue ideal assignment, we may need to consider
preempting the low priority application containers first.
