Li Lu created YARN-5739:
---------------------------
Summary: Provide timeline reader API to list available timeline
entity types for one application
Key: YARN-5739
URL: https://issues.apache.org/jira/browse/YARN-5739
Project: Hadoop YARN
Issue Type: Sub-task
Components: timelinereader
Reporter: Li Lu
Assignee: Li Lu
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.
