[jira] [Updated] (YARN-1493) Schedulers don't recognize apps separately from app-attempts

     [ https://issues.apache.org/jira/browse/YARN-1493?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
