[jira] [Commented] (YARN-2975) FSLeafQueue app lists are accessed without required locks

    [ https://issues.apache.org/jira/browse/YARN-2975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15022796#comment-15022796 ] 

Sangjin Lee commented on YARN-2975:
-----------------------------------

I think we should backport this to branch-2.6. This is a very important follow-up fix to YARN-2910. [~kasha]?

> YARN-2910 adds explicit locked access to runnable and non-runnable apps in FSLeafQueue. As FSLeafQueue has getters for these, they can be accessed without locks in other places.
