Sangjin Lee commented on YARN-2928:
-----------------------------------
Thanks [~vinodkv] for putting the plan together! Some quick questions:
- Phase 1: what are the "ApplicationMaster events"? Is it the lifecycle of the
AM container or AMs like MR AMs emitting framework-specific events/metrics?
- Phase 3: would it be possible to pull in the RM events bit earlier than phase
3? I don't think it would be that difficult to do, and it would serve as a very
useful data point. Thoughts?
- Are we thinking of merging only after all phases are complete, or could there
be meaningful intermediate checkpoints we can merge? It would be good if we
could achieve the latter.
