Vrushali C commented on YARN-4173:
----------------------------------
In YARN-5747, the final aggregation is being done explicitly, so need to think
over further what else we need to do here. I believe what needs to be confirmed
is that these are tagged with FINAL tags when they are written.
> Ensure the final values for metrics/events are emitted/stored at APP
> completion time

> When an application is finishing, the final values of metrics/events need to
> be written to the backend as final values from the all AM/RM/NM processes for
> that app.
> For the flow run table (YARN-3901), we need to know which values are the
> final ones for metrics so that they can be tagged accordingly.
