-----------------------------
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:
