Vinod Kumar Vavilapalli updated YARN-1493:
------------------------------------------
Description:
Today, scheduler is tied to attempt only.
We need to separate app-level handling logic in scheduler. We can add new
app-level events to the scheduler and separate the app-level logic out. This is
good for work-preserving AM restart, RM restart, and also needed for
differentiating app-level metrics and attempt-level metrics.
