             Summary: EntityGroupFSTimelineStore to not log errors during 
shutdown
                 Key: YARN-4695
                 URL: https://issues.apache.org/jira/browse/YARN-4695
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
    Affects Versions: 2.8.0
            Reporter: Steve Loughran


# The {{EntityGroupFSTimelineStore}} threads log exceptions that get raised 
during their execution.
# the service stops by interrupting all its workers
# as a result, the workers all log exceptions at error *even during a managed 
shutdown*
# this creates distracting noise in logs
