Subject [jira] [Commented] (YARN-3873) pendingApplications in LeafQueue should also use OrderingPolicy
Date Fri, 07 Aug 2015 18:11:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-3873?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14662181#comment-14662181

Wangda Tan commented on YARN-3873:

Hi [~sunilg],
Sorry for confusing you in my last comment, what I meant is not hard code FifoOrderingPolicy
for ALL policies, what I meant is to use the same OrderingPolicy for pendingApplications.
For example, when policy=fair, pendingApps & runningApps use FairOrderingPolicy, when
policy=fifo, pendingApps & runningApps use FifoOrderingPolicy.

> Currently *pendingApplications* in LeafQueue is using {{applicationComparator}} from
CapacityScheduler. This can be changed and pendingApplications can use the OrderingPolicy
configured in Queue level (Fifo/Fair as configured).
