Subject [jira] [Commented] (YARN-4044) Running applications information changes such as movequeue is not published to TimeLine server
Date Wed, 09 Sep 2015 17:56:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14737303#comment-14737303

Sunil G commented on YARN-4044:
-------------------------------

Thank you [~Naganarasimha Garla] for the input.

Idea of publish each app changed event  (priority/queue) is good. But current V1 GUI doesnt
have support to display all changed entities of application in UI. I discussed with [~jianhe]
also offline. As per our discussion, we need not need to concentrate on showing this changed
entities in UI now. It will make current UI complex. In future UI work, we can handle this
in a better human readable form (application timelilne graph maybe). However we can have changed
events  in YARN level rather than entity overwrite, and we can show last changed event for
now. I will update a patch based on this understanding.
