----------------------------------
Hi [~zjshen]
I have re-assigned the jira to myself since the timeline service folks in the
community are having an active discussion on this aspect. Please let me know if
you want to take the jira back.
thanks

> Timeline entity uniqueness

> Key: YARN-3588
> URL: https://issues.apache.org/jira/browse/YARN-3588

> In YARN-3051, we have some discussion about how to uniquely identify an
> entity. Sangjin and some other folks propose to only uniquely identify an
> entity by <type, id> in the scope of a single app. This is different from
> entity uniqueness in ATSv1, where <type, id> can globally identify an entity.
> This is going to affect the way of fetching a single entity, and raise the
> compatibility issue. Let's continue our discussion here to unblock YARN-3051.
