Subject [jira] [Commented] (YARN-4997) Update fair scheduler to use pluggable auth provider
Date Thu, 11 Aug 2016 02:00:27 GMT

    [ https://issues.apache.org/jira/browse/YARN-4997?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15416362#comment-15416362

Tao Jie commented on YARN-4997:

[~templedf], thanks for reply! For {{getDefaultPermissions()}}, there is no reentrant problem
since this method is only invoked by {{reloadAllocation()}}, which is already synchronized.
The intermediate variable is used here is to avoid potential thread safety problem (Actually,
 it is not necessary) .
 {{public}} keyword in {{onReload}} method here is removed since it trigger a checkstyle warning.
It's ok to keep it.
Update the patch, please take a quick review!
