Stephan Ewen created FLINK-5232: ----------------------------------- Summary: 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 Fix For: 1.1.3
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} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
