> Key: FLINK-23843
> URL: https://issues.apache.org/jira/browse/FLINK-23843
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Common
> Affects Versions: 1.13.2, 1.15.0, 1.14.4
> Reporter: Stephan Ewen
> Assignee: Etienne Chauchot
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.15.0
>
>
> Currently, when a the method
> "SplitEnumeratorContext.runInCoordinatorThread()" throws an exception, the
> effect is a process kill of the JobManager process.
> The chain how the process kill happens is:
> * An exception bubbling up in the executor, killing the executor thread
> * The executor starts a replacement thread, which is forbidden by the thread
> factory (as a safety net) and causes a process kill.
> We should prevent such exceptions from bubbling up in the coordinator
> executor.
