Subject [jira] [Commented] (YARN-5739) Provide timeline reader API to list available timeline entity types for one application
Date Thu, 01 Dec 2016 00:38:59 GMT

    [ https://issues.apache.org/jira/browse/YARN-5739?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15710357#comment-15710357

Li Lu commented on YARN-5739:
-----------------------------

bq. I hate to nitpick on the name, but AbstractTimelineStorageReader sounds a little awkward
to me. Can we stick to the entity reader names? How about AbstractTimelineEntityReader or
BaseTimelineEntityReader? Thoughts?
Avoiding the term "Entity" is a deliberate choice here. Now EntityTypeReader will not return
any entity types so I'm avoiding using the term Entity in the base class.

> 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.
