Subject [jira] [Commented] (YARN-4511) Common scheduler changes supporting scheduler-specific implementations
Date Mon, 23 Oct 2017 18:15:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-4511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16215566#comment-16215566

Miklos Szegedi commented on YARN-4511:

Thank you, [~haibochen] for the patch.
342	    // notify schedulerNode of the update to correct resource accounting
343	    node.containerUpdated(existingRMContainer, existingContainer);
345	    ((RMContainerImpl)tempRMContainer).setContainer(updatedTempContainer);
346	    // notify SchedulerNode of the update to correct resource accounting
347	    node.containerUpdated(tempRMContainer, tempContainer);
I think these still need to be atomic from the perspective of the node. It may happen that
there is an allocation decision before the release and after reacquiring the resources here.
This may lead to double allocation of the same resources on the node.
