Subject [jira] [Updated] (YARN-1493) Separate app-level handling logic in scheduler
Date Wed, 11 Dec 2013 05:15:10 GMT

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

Jian He updated YARN-1493:
--------------------------

    Description: 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.
