Subject Re: How flink monitor source stream task(Time Trigger) is running?
Date Fri, 29 Sep 2017 13:01:48 GMT
Any exception thrown by your SourceFunction will be caught by Flink and that will mark a task
(that was executing this SourceFuntion) as failed.

If you started some custom threads in your SourceFunction, you have to manually propagate
their exceptions to the SourceFunction.
