> Key: FLINK-20081
> URL: https://issues.apache.org/jira/browse/FLINK-20081
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Common
> Reporter: Jiangjie Qin
> Priority: Major
> Fix For: 1.12.0
>
>
> Currently the {{ExecutorNotifier}} runs the {{handler}} in the worker thread
> if there is an exception thrown from the {{callable}}. This breaks the
> threading model and prevents an exception from bubbling up to fail the job.
> Another issue is that right now, when an exception bubbles up from the
> {{SourceCoordinator}}, the UncaughtExceptionHandler will call
> System.exit(-17) and kill the JM. This is too much. Instead, we should just
> fail the job to trigger a failover.
