Rohith Sharma K S commented on YARN-4220:
-----------------------------------------
Multiple application entity reader enforces to provide userId and flowName as a
filter. It looks like userId and flowName are tightly coupled for multiple
applications retrieval.
> [Storage implementation] Support getEntities with only Application id but no
> userId

> Currently we're enforcing flow and flowrun id to be non-null values on
> {{getEntities}}. We can actually query the appToFlow table to figure out an
> application's flow id and flowrun id if they're missing. This will simplify
> normal queries.
