[jira] [Commented] (YARN-6124) Make SchedulingEditPolicy can be enabled / disabled / updated with RMAdmin -refreshQueues

["Wangda Tan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-6124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16216020#comment-16216020 ] 

Wangda Tan commented on YARN-6124:
----------------------------------

Just changed title of this JIRA to address the SchedulingEditPolicy changes. 

My proposal: 
Lifecycle of SchedulingEditPolicy/SchedulingMonitor should be a part of scheduler's logic instead of RMActiveService. 

We should make changes to AbstractYarnScheduler to load and manage SchedulingEditPolicy from config. And inside {{reinitialize}}, we should check changes to SchedulingEditPolicy and start/stop SchedulingMonitor when needed. 

Thoughts? [~curino]/[~eepayne]/[~jlowe].

> Now enabled / disable / update SchedulingEditPolicy config requires restart RM. This is inconvenient when admin wants to make changes to SchedulingEditPolicies.
