[jira] [Commented] (YARN-6322) Disable queue refresh when configuration mutation is enabled

    [ https://issues.apache.org/jira/browse/YARN-6322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16069091#comment-16069091 ] 

Jonathan Hung commented on YARN-6322:
-------------------------------------

Attached a patch to disable -refreshQueues if scheduler is a MutableConfScheduler, and its configuration is mutable.

[~xgong] and [~leftnoteasy], do you mind taking a look ? Thanks!

> When configuration mutation is enabled, the configuration store is the source of truth. Calling {{-refreshQueues}} won't work as intended, so we should just disable this.
