问题
We noticed on our kafka broker logs that our stream applications are trying to describe topics that are not part of the topology. It looks like it is periodically happening every 10 minutes.
Why is this occurring? Why does streams need to know about topics that are not part of the topology? Anyway to stop this? Since the stream app does not have access to describe those topics we are getting a bunch of error logs.
We are using version 1.1.1

It's a know issue, that will get fixed in the 2.5 release: https://issues.apache.org/jira/browse/KAFKA-7317
