[jira] [Commented] (YARN-1506) Replace set resource change on
RMNode/SchedulerNode directly with event notification.
[ https://issues.apache.org/jira/browse/YARN-1506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15173716#comment-15173716 ]

----------------------------------
Hi Junping Du, thanks for your work.
I tested this feature in HA. When switching from RM1 to RM2, all the update information would be lost.
RM2 will recovery the NM's resource configuration as it registered. Right?
