[~till.rohrmann] this issues past a long time, any opinion?
> Add a Thread default uncaught exception handler on the JobManager

> Key: FLINK-5232
> URL: https://issues.apache.org/jira/browse/FLINK-5232
> Project: Flink
> Issue Type: Sub-task
> Components: JobManager
> Reporter: Stephan Ewen
> Assignee: vinoyang
> Priority: Major
>
> When some JobManager threads die because of uncaught exceptions, we should bring down the JobManager. If a thread dies from an uncaught exception, there is a high chance that the JobManager becomes dysfunctional.
> The only sfae thing is to rely on the JobManager being restarted by YARN / Mesos / Kubernetes / etc.
> I suggest to add this code to the JobManager launch:
> {code}
> Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler() {
> @Override
> public void uncaughtException(Thread t, Throwable e) {
> try {
> LOG.error("Thread {} died due to an uncaught exception. Killing process.", t.getName());
> } finally {
> Runtime.getRuntime().halt(-1);
> }
> }
> });
> {code}
