Kafka Streams列表和尝试描述的主题不是拓扑的一部分 [英] Kafka Streams Listing and Trying describe topics not part of the topology

问题描述

我们在kafka代理日志中注意到，我们的流应用程序正在尝试描述不属于拓扑的主题.似乎每隔10分钟就会发生一次.

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.

为什么会这样?为什么流需要了解不属于拓扑的主题?无论如何要停止吗?由于流应用程序无权描述这些主题，因此我们会收到一堆错误日志.

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.

我们正在使用1.1.1版

We are using version 1.1.1

推荐答案

这是一个已知问题，将在2.5版本中得到解决:

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