      Description

      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:

      2014-02-17 08:23:21,240 ERROR org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler: Request for appInfo of unknown attemptappattempt_1392419715319_0135_000001
