ASF GitHub Bot commented on FLINK-2499: --------------------------------------- GitHub user mbalassi opened a pull request: https://github.com/apache/flink/pull/1071 [FLINK-2499] [scripts] Warning message for hosts starting multiple da… …emons As per the discussion on the relevant [ticket](https://issues.apache.org/jira/browse/FLINK-2499) adds a warning message. I decided against the latest comment of @StephanEwen on the issue, because I have also run into (accidentally) trying to stack multiple JobManagers on the same machine and it is nice to have this warning even in that case. This solution is a bit too verbose in test setups with a lot of TaskManagers on the same machine, but keeps the PID related code in the `flink-daemon.sh`.
