Li Lu commented on YARN-4224:
-----------------------------
Thanks [~leftnoteasy]! I agree that we should separate the semantics and
implementations. Our web UI, as one user of the REST API, does not really need
general queries for timeline entities (I can always attach an entity type if
needed). However, as from the API design perspective, I'd hope our API to be
general enough. Having APIs like "list all entities within one application" may
seems too ambitious for implementations, but something like "on this end point
I assume you want all entities for this application, but to avoid crash myself
I'm only returning a part of it" looks fine. However, enforcing an entity type
to all such queries and add them as part of the end point looks a little bit
suboptimal (it also changes the way we organize resources).
