[jira] [Created] (FLINK-8884) The DispatcherThreadFactory should
register uncaught exception handlers
Stephan Ewen created FLINK-8884:
-----------------------------------
Summary: The DispatcherThreadFactory should register uncaught exception handlers
Key: FLINK-8884
URL: https://issues.apache.org/jira/browse/FLINK-8884
Project: Flink
Issue Type: Bug
Components: TaskManager
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 1.5.0, 1.6.0
The {{DispatcherThreadFactory}} is responsible for spawning the thread pool threads for TaskManager's async dispatcher and for the CheckpointCoordinators timed trigger.
In case of uncaught exceptions in these threads, the system is not healthy and more, hence they should register the {{FatalExitUcaughtExceptionsHandler}}.
