[jira] [Commented] (SAMZA-382) SamzaContainer main thread might die
without proper cleanup
[ https://issues.apache.org/jira/browse/SAMZA-382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14097841#comment-14097841 ]
Chris Riccomini commented on SAMZA-382:
---------------------------------------
bq. The result is that, the AMF thread can still be alive - thus locking up resources in YARN.
One minor note: the thread is the JMX server (non-daemon) thread, not the AMF one (which is an internal metrics thing at LI :)).

> Key: SAMZA-382
> URL: https://issues.apache.org/jira/browse/SAMZA-382
> Project: Samza
> Issue Type: Bug
> Components: container
> Affects Versions: 0.8.0
> Reporter: Chinmay Soman
> Fix For: 0.8.0
>
>
> In SamzaContainer,
> There are some method invocations within 'main' that throw an exception:
> For eg: getTaskNameToSystemStreamPartition (this might happen if there is no SSP for a given task).
> However, this is outside the try block due to which, it doesn't cleanup properly before dying. The result is that, the AMF thread can still be alive - thus locking up resources in YARN.
> Proposed resolution: Include all such statements within the try block
