Subject [jira] [Commented] (YARN-4406) RM Web UI continues to show decommissioned nodes even after RM restart
Date Wed, 02 Dec 2015 21:03:10 GMT

    [ https://issues.apache.org/jira/browse/YARN-4406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15036616#comment-15036616
] 

Kuhu Shukla commented on YARN-4406:
-----------------------------------

I agree. I was thinking about that too. During {{registerwithRM()}} we throw a YarnException
while on the ResourceTrackerService side we just send NodeAction as SHUTDOWN. We could in
fact update InactiveRMNode list with this node, so that it is consistent. Let me know what
you think. I will put up a patch soon.

> If you start up a cluster, decommission a NodeManager, and restart the RM, the decommissioned
node list will still show a positive number (1 in the case of 1 node) and if you click on
the list, it will be empty.
