启动Kafka-Connect时，我看到很多警告

一些帖子说这是因为主题创建被禁用了，但是在我看来并不是这样。仍然创建存储主题。

另一个人提到它的版本不匹配，就我而言也不是这样。 kafka代理版本为1.0.0，而Kafka-Connect与以下pom.xml相同。这些配置是在Kafka-Connect启动期间提供的

为修复这些警告，我还应该检查什么？我可以看到数据是通过Kafka-Connect传递的，但仍然担心这些警告

Answer 1

这些仅仅是WARN的形式，可以忽略。在将来的版本中，它们将被正确删除：https://github.com/apache/kafka/pull/5876

Kafka connect：提供了配置XXX，但不是AdminClientConfig中的已知配置
