Subject [jira] [Commented] (YARN-4074) [timeline reader] implement support for querying for flows and flow runs

Varun Saxena commented on YARN-4074:
------------------------------------

The 2nd point I guess even I can handle even in YARN-4075. I can verify limit and if its 0
or negative, forward null to storage layer. If its null, DEFAULT_LIMIT will be applied.
