Jungtaek Lim commented on STORM-1915:
-------------------------------------
STORM-1934 is applied to 1.0.2 but I just forgot to close this.
[~fogetti]
Please try out 1.0.2 and see it works without the symptom, and reopen if it's
not. Thanks!
> Supervisor keeps restarting forever

> Key: STORM-1915
> URL: https://issues.apache.org/jira/browse/STORM-1915
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 1.0.1
> Environment: Linode 4GB running on KVM - Ubuntu 14.04 LTS
> Reporter: Gergely Nagy
>
> While submitting a topology to a 20 node 40 worker strong cluster, the
> supervisor keeps throwing errors and keeps restarting the workers it is
> supervising.
> For this reason the topology never starts, instead it keeps dancing by
> reassigning the bolts and spouts forever.
> I'd love to attach the logs here but I can't find any upload button in the
> JIRA form.
> The error basically says:
> {code}
> 2016-06-18 12:04:26.589 o.a.s.config [WARN] Failed to get worker user for .
