Jonathan Hung commented on YARN-10263:
--------------------------------------
My understanding is that the sequence looks like:
(1) app finishes -> (2) app saved to state store -> (3) app summary is logged
I think if we only check that an app is recovered or not, we will miss some
apps if the RM is restarted between states 2 and 3. We would somehow need to
tell the state store whether something has been logged, but it seems a bit
overkill to add a new event for this.
Any other thoughts?
