Subject [jira] [Commented] (YARN-5699) Retrospect container entity fields which are publishing in events info fields.
Date Thu, 06 Oct 2016 09:02:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15551391#comment-15551391

Rohith Sharma K S commented on YARN-5699:

I think this is the time to decide should we support translation layer for YARN entities to
get attempts-report, container-reports, application-report. It can be additional web service
in ATS2 similar to */ws/v1/applicationhistory*.

Major concern of this  JIRA is about deserializing attempt-report and container-report for
Web UI. If we get much easier translation layer from java, it would be much easier. Other
wise, it is tedious task for deserializing entity payload if any change in the publishing

> 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.
