Sangjin Lee commented on YARN-5699: ----------------------------------- bq. What about end time? End time has to be get from event time stamp. But anyway, I have added a comment for streamlining YARN entities publishing, I think we should decide for providing YARN entities converter rather than fixing individual many bugs. Created time is a first-class attribute of an entity, so it would be good to use that instead of a generic entity info field. End time is not a first-class attribute, so entity info would be a natural place. {quote} Actually let's take one step backward... What is the key benefit for keeping most data in event info, rather than in entity info? To me, storing data in entity info map looks a good representation that the data "belongs to" the whole entity, but not just one event. Even though some data may come from a certain type of timeline event, if it adds useful information to the whole entity, we should put them in entity info field. I'm not sure if there are some implementation side concerns that prevent us from doing this. However, even if so, I believe we should fix those blockers but not solve the problem the other way around (avoid putting data in entity info, but just put them in event info). I would de-prioritize the work on making the v2 code path consistent with v1's if this is a problem for our current design. {quote} I'm not so sure if I understand what you meant by this. Are you proposing elevating all event info items to the entity info unless they really belong only to events? Or are you proposing not to do this work? Bit confused... > Retrospect yarn entity fields which are publishing in events info fields. > ------------------------------------------------------------------------- > > Key: YARN-5699 > URL: https://issues.apache.org/jira/browse/YARN-5699 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Rohith Sharma K S > Assignee: Rohith Sharma K S > Attachments: 0001-YARN-5699.YARN-5355.patch, 0001-YARN-5699.patch, > 0002-YARN-5699.YARN-5355.patch > > > Currently, all the container information are published at 2 places.

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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
