Subject [jira] [Commented] (YARN-2393) Fair Scheduler : Implement static fair share
Date Mon, 11 Aug 2014 20:00:15 GMT

    [ https://issues.apache.org/jira/browse/YARN-2393?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14093217#comment-14093217

Ashwin Shankar commented on YARN-2393:
--------------------------------------

[~ywskycn],
On skimming through the patch at high level, I had a quick comment. Apart from the configuration
in alloc xml, queues can get created dynamically when one uses QueuePlacementRules like primary
group, nested user queue etc. with create="true". Shouldn't we recompute static shares in
these cases ?

> Static fair share is a fair share allocation considering all(active/inactive) queues.It
would be shown on the UI for better predictability of finish time of applications.
> We would compute static fair share only when needed, like on queue creation, node added/removed.
Please see YARN-2026 for discussions on this.
