https://issues.apache.org/jira/browse/STORM-3013
The above JIRA item explains an issue that we see very frequently when shutting down our Storm topology. The listed fix versions are 2.0.0 and 1.2.3, both of which I don't believe have been officially released. Is there a workaround for this issue in the mean time? I don't think it is a critical issue, but it would be nice to not always get these messages in our logs.
