Sangjin Lee commented on YARN-3864:
-----------------------------------

Yes, the apps query (and therefore the application table) is the most natural 
place to query for all apps for a flow run. The flow run table is mainly for 
handling real-time aggregation, and should be considered secondary for this 
purpose.

> Implement support for querying single app and all apps for a flow run
