Date Thu, 05 May 2016 23:47:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-5046?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15273324#comment-15273324

Ray Chiang commented on YARN-5046:
----------------------------------

[~leftnoteasy] or [~jianhe], let me know if you think if it makes sense to make YARN-4433
a sub-task of this JIRA.  I'm also looking at YARN-3890 and YARN-2773 as possible candidates.

>             Project: Hadoop YARN
>          Issue Type: Task
>          Components: capacity scheduler, fairscheduler, resourcemanager, scheduler
>    Affects Versions: 3.0.0

> At this point in time, there are several places where code common to the schedulers can
be moved from one or more of the schedulers into AbstractYARNScheduler or a related interface.
> Creating this umbrella JIRA to track this refactoring.  In general, it is preferable
to create a subtask JIRA on a per-method basis.
> This may need some coordination with [YARN-3091  \[Umbrella\] Improve and fix locks of
RM scheduler|https://issues.apache.org/jira/browse/YARN-3091].
