[jira] [Commented] (YARN-6636) Fair Scheduler: respect node labels
at resource request level
[ https://issues.apache.org/jira/browse/YARN-6636?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16572100#comment-16572100 ]
Brandon Scheller commented on YARN-6636:
----------------------------------------
For clarification, this is simply supporting resource request based node labels for Fair-Scheduler correct?
Essentially giving all queues access to all node labels and allowing the Application/ResourceRequest labels to dictate individual node scheduling.
Am I understanding correctly that this would not affect queue management or fair share calculations at all and would leave it to the user to setup queues/labels properly?
