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

             Summary: TaskManager should commit suicide after cancellation failure
                 Key: FLINK-4715
                 URL: https://issues.apache.org/jira/browse/FLINK-4715
             Project: Flink
          Issue Type: Improvement
          Components: TaskManager
    Affects Versions: 1.2.0
            Reporter: Till Rohrmann
             Fix For: 1.2.0


In case of a failed cancellation, e.g. the task cannot be cancelled after a given time, the {{TaskManager}} should kill itself. That way we guarantee that there is no resource leak.

This behaviour acts as a safety-net against faulty user code.
