----------------------------------

             Summary: Decrease logging verbosity of StackTraceSampleCoordinator
                 Key: FLINK-3535
                 URL: https://issues.apache.org/jira/browse/FLINK-3535
             Project: Flink
          Issue Type: Improvement
          Components: Webfrontend
            Reporter: Ufuk Celebi
            Assignee: Ufuk Celebi
            Priority: Minor


Logging in StackTraceSampleCoordinator is verbose and can possible confuse users, for example if a task manager dies, you see time out messages. Let's log these on DEBUG level as they are only relevant if something fishy is going on and the user has an interest in understanding what the issue is.
