Hi,
so you tried to stop flink by killing the processes?
I assume you've started Flink in the standalone cluster mode?
If you a kill, and a kill -9 should definitively stop Flink.
Did you check the log files of the task manager? The Flink services are
logging when they are receiving signals from the operating system. If the
cancelling doesn't work for some reason, it'll be logged as well.
In general, I would recommend cancelling the job from the CLI or web
interface. In some cases, the job might not stop, for example when the user
code is blocking all the time (a good example is a while(true){} loop that
doesn't get stopped from a cancel() call).
What is your Flink job doing? Does it contain a custom source?
