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

             Summary: Pull ExecutionService lifecycle management out of the JobManager
                 Key: FLINK-5082
                 URL: https://issues.apache.org/jira/browse/FLINK-5082
             Project: Flink
          Issue Type: Bug
          Components: JobManager
    Affects Versions: 1.1.3, 1.2.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.2.0, 1.1.4


The {{JobManager}} receives an {{ExecutorService}} to run its futures as a constructor parameter. Even though the {{ExecutorService}} comes from outside, the {{JobManager}} shuts the executor service down if the {{JobManager}} terminates. This is clearly a sub-optimal behaviour leading also to {{RejectedExecutionExceptions}}.

I propose to move the {{ExecutorService}} lifecycle management out of the {{JobManager}}.
