Subject [jira] [Created] (YARN-1785) FairScheduler treats app lookup failures as ERRORs
Date Wed, 05 Mar 2014 01:21:43 GMT
bc Wong created YARN-1785:
-----------------------------

             Summary: FairScheduler treats app lookup failures as ERRORs
                 Key: YARN-1785
                 URL: https://issues.apache.org/jira/browse/YARN-1785
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.2.0
            Reporter: bc Wong


When invoking the /ws/v1/cluster/apps endpoint, RM will eventually get to RMAppImpl#createAndGetApplicationReport,
which calls RMAppAttemptImpl#getApplicationResourceUsageReport, which looks up the app in
the scheduler, which may or may not exist. So FairScheduler shouldn't log an error for every
lookup failure:
