> Project: Samza
> Issue Type: Bug
> Components: container
> Affects Versions: 0.6.0
> Reporter: Chris Riccomini
> Assignee: Chris Riccomini
> Attachments: SAMZA-130.0.patch

>
> If a failure occurs anywhere in the init phase of the SamzaContainer, the
> exception is never caught, and shutdown is never called on the task, or any
> of the consumers/producers.
> This causes the SamzaContainer to hang if there are non-daemon threads
> running. We should make a best-effort attempt to catch exceptions during the
> init phase, and call shutdown on everything before exiting.
> We should also take care to exit with a non-zero exit code when an exception
> is thrown and caught, so the YARN AM properly figures out that the container
> failed, and didn't complete successfully.
