Subject [jira] [Commented] (YARN-5699) Retrospect yarn entity fields which are publishing in events info fields.
Date Mon, 10 Oct 2016 21:46:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15563620#comment-15563620

Li Lu commented on YARN-5699:
-----------------------------

Thanks for the work [~rohithsharma]! Generally fine but a few concerns:
1. I agree with Varun and Sangjin that we may need to think twice about diagnostic info. This
field is way too cumbersome for users to directly query. I think it's fine to leave it in
event info. 
2. When we get app state updated event, we may want to post the event info as is, but at the
same time update entity level information?
3. A bigger concern is on the code itself. Right now we have a lot of info key name constants
ending as "EVENT_INFO", but actually we no longer use them as event info. Instead, we may
post them as entity info, or event info, or both. We need to update or simplify those constants
to make them less confusing.

> Currently, all the container information are published at 2 places. Some of them are
at entity info(top-level) and some are  at event info. 
> For containers, some of the event info should be published at container info level. For
example : container exist status, container state, createdTime, finished time. These are general
information to container required for container-report. So it is better to publish at top
level info field.
