-----------------------------
Summary: Separate app-level handling logic in scheduler
Key: YARN-1493
URL: https://issues.apache.org/jira/browse/YARN-1493
Project: Hadoop YARN
Issue Type: Sub-task
Environment: Today, scheduler is tied to attempt only. 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.
