Sangjin Lee updated YARN-4074:
------------------------------
Attachment: YARN-4074-YARN-2928.POC.001.patch
Posting a v.1 POC patch. This implements the first query (the flow activity
query). I'll follow it up with another one tomorrow that implements the second
one too.
This is to get the design choices and correctness reviewed first. It does
- include the flow activity query as part of getEntities()
- create a data container for the flow activity table called FlowActivityEntity
It probably needs a fair amount of refactoring to make the reader code more
manageable. Also, I need to add unit tests. They will come later.
> [timeline reader] implement support for querying for flows and flow runs
