Date Thu, 13 Jul 2017 17:30:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16086052#comment-16086052

Yufei Gu commented on YARN-6769:

Hi [~daemon], we usually put contributor's name in git logs, something like "YARN-6769. xxxx
(Daemon via Yufei Gu)". I assume daemon is not your really name. Do you want to use your really
name in the git log? If Yes, please send me your name. Thanks.

> When use fairsheduler as RM scheduler, before assign container we will sort all queues
or applications. 
> We will use FairSharePolicy#compare as the comparator´╝î but the comparator is not so
> It have a problem as blow:
> 1. when a queue use resource over minShare(minResources), it will put behind the queue
whose demand is zeor.
> so it will greater opportunity to get the resource although it do not want. It will waste
schedule time when assign container
> to queue or application.
> I have fix it, and I will upload the patch to the jira.
