Jungtaek Lim commented on STORM-1879:
-------------------------------------
[~kevinconaway] I guess yes, since STORM-1934 is applied to 1.0.2. I just
forgot to close related issues.
Please try out 1.0.2 and see it works without the symptom, and reopen if it's
not. Thanks!
> Supervisor may not shut down workers cleanly

> Key: STORM-1879
> URL: https://issues.apache.org/jira/browse/STORM-1879
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 1.0.1
> Reporter: Stig Rohde Døssing
> Attachments: fix_missing_worker_pid.patch, nimbus-supervisor.zip,
> supervisor.log
>
>
> We've run into a strange issue with a zombie worker process. It looks like
> the worker pid file somehow got deleted without the worker process shutting
> down. This causes the supervisor to try repeatedly to kill the worker
> unsuccessfully, and means multiple workers may be assigned to the same port.
> The worker root folder sticks around because the worker is still heartbeating
> to it.
> It may or may not be related that we've seen Nimbus occasionally enter an
> infinite loop of printing logs similar to the below.
