[jira] [Commented] (YARN-1676) Make admin refreshUserToGroupsMappings of configuration work across RM failover

    [ https://issues.apache.org/jira/browse/YARN-1676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13888747#comment-13888747 ] 

Vinod Kumar Vavilapalli commented on YARN-1676:
-----------------------------------------------

The point of "refreshUserToGroupsMappings" call is that the user-to-group mappings as returned by the GroupMappingProvider have changed (locally or remotely). So the test should also simulate an addition/removal of a user's group and validate the same after refresh.
