bq. Moreover, REST endpoint suggestion was both entity-types and entitytypes. I
am fine with both as we do use hyphen in other REST endpoints in YARN. Let us
go with majority opinion.
Right now I'm following our practices in node label related web services in the
RM. Please do let me know if the hyphens will cause any troubles. Thanks!

> Right now we only show a part of available timeline entity data in the new
> YARN UI. However, some data (especially library specific data) are not
> possible to be queried out by the web UI. It will be appealing for the UI to
> provide an "entity browser" for each YARN application. Actually, simply
> dumping out available timeline entities (with proper pagination, of course)
> would be pretty helpful for UI users.
> On timeline side, we're not far away from this goal. Right now I believe the
> only thing missing is to list all available entity types within one
> application. The challenge here is that we're not storing this data for each
> application, but given this kind of call is relatively rare (compare to
> writes and updates) we can perform some scanning during the read time.
