Vrushali C commented on YARN-3588:

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

> 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.
