Subject [jira] [Commented] (YARN-6243) CapacityScheduler: canAssignToThisQueue should be called only when necessary
Date Tue, 28 Feb 2017 03:06:45 GMT

    [ https://issues.apache.org/jira/browse/YARN-6243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15887143#comment-15887143
] 

Sunil G commented on YARN-6243:
-------------------------------

During async sync thread allocation, is it possible that queue used may be changed?
If queue used is not changed, may {{canAssignToThisQueue}} need not have to be invoked provided
there are no resource changes in cluster (add/remove node). Is this what you are also thinking?

> Now canAssignToThisQueue is called when iterating apps in a LeafQueue, we should optimize
this.
