Subject [jira] [Commented] (YARN-1459) Handle supergroups, usergroups and ACLs across RMs during failover
Date Sat, 14 Dec 2013 01:10:07 GMT

    [ https://issues.apache.org/jira/browse/YARN-1459?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13848122#comment-13848122
] 

Arpit Gupta commented on YARN-1459:
-----------------------------------

Another thing that would help users is we could provide a config servlet on the RM that would
show all these configs. Thus the user can very easily determine what configs RM is running
with. This would also help with testing as you would now just need a way to determine if the
new configs got loaded versus making sure the new acl's are being enforced or not.

> The supergroups, usergroups and ACL configurations are per RM and might have been changed
while the RM is running. After failing over, the new Active RM should have the latest configuration
from the previously Active RM.
