messages mean, and I'm not confident on the setup. What do these messages mean? Have I misconfigured something?

推荐答案
您看到的消息还不是错误. Zookeeper提出了一个潜在的异常，即发出请求的原始对象必须处理.
The message you see is not an error yet. It is a potential exception raised by Zookeeper that original object making a request has to handle.
启动新的Kafka时，会收到一堆NoNode消息.这很正常，因为某些路径尚不存在.同时，由于路径已经存在，您还会收到NodeExists消息.
When you start a fresh Kafka, it gets a bunch of NoNode messages. It's normal because some paths don't exist yet. At the same time, you get also NodeExists messages as the path exists already.
示例:Error:KeeperErrorCode = NoNode for /config/topics/test
这是因为Kafka向Zookeeper发送了此路径的请求.但是它不存在.可以，因为您正在尝试创建它.因此，您从Zookeeper中看到"INFO"，但从Kafka中没有看到错误.一旦Kafka收到此消息，它将尝试创建您的主题.为此，它需要访问Zookeeper中的主题路径.因此，它发送一个请求并得到错误NodeExists for /config/topics.同样，这是正常现象，Kafka会忽略该消息.
Example: Error:KeeperErrorCode = NoNode for /config/topics/test
It's because Kafka sends a request to Zookeeper for this path. But it doesn't exist. That's OK, because you are trying to create it. So, you see "INFO" from Zookeeper but no error from Kafka. Once Kafka gets this message, it tries to create your topic. To do so, it needs to access a path in Zookeeper for topics. So, it sends a request and gets an error NodeExists for /config/topics. Again, it's normal and Kafka ignores the message.
长话短说，这些都是非问题消息，您应该跳过它们.如果您不满意，请更改Zookeeper的日志记录配置(不过不建议这样做).
Long story short, these are all non-issue messages and you should skip them. If it bothers you, change logging configuration of Zookeeper (it's not recommended though).
