> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Reporter: Robert Metzger

> Labels: starter
>
> It would make debugging Flink errors easier if we would intercept and log
> calls to System.exit() through the SecurityManager.
> A user recently had an error where the JobManager was shutting down because
> of a System.exit() in the user code:

> If I remember correctly, we had such issues before.
> I put this ticket into the "Runtime / Coordination" component, as it is
> mostly about improving the usability / debuggability in that area.
