Maximilian Michels commented on FLINK-3753:
-------------------------------------------
Thanks for reporting! It actually states in the class why the {{stop()}} method
is used. I think we have to work around some issues with the Kafka fetcher.
I would close this issue for now because we want to use {{stop()}} for the
KillerWatchDog (scary name!).
> KillerWatchDog should not use kill on toKill thread
