Subject [jira] [Updated] (YARN-3102) Decommisioned Nodes not listed in Web UI
Date Wed, 27 Jan 2016 19:06:39 GMT

     [ https://issues.apache.org/jira/browse/YARN-3102?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Kuhu Shukla updated YARN-3102:
    Attachment: YARN-3102-v7.patch

Thanks a lot [~jlowe] for the very useful comments and help. I have updated the patch to have
a default DrainDispatcher for MockRM. Also reduced the containsKey-get-remove to a remove
 and get-remove to remove in RMNodeImpl. I fixed 2 test classes where the drainDispatcher
was following older code style along with the writetoHostFile change. Test cases' timeouts
are now 30 seconds.
