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

             Summary: Unstable Yarn tests due to Akka Shutdown Exception Logging
                 Key: FLINK-8374
                 URL: https://issues.apache.org/jira/browse/FLINK-8374
             Project: Flink
          Issue Type: Bug
          Components: Tests
    Affects Versions: 1.4.0
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
            Priority: Critical
             Fix For: 1.5.0


Akka may log the following in some cases during shutdown:

{{java.util.concurrent.RejectedExecutionException: Worker has already been shutdown}}

The Yarn tests search the logs for unexpected exceptions and fail when encountering that exception. We should whitelist it, as it is not a problem, merely an Akka shutdown artifact.
