Question

我正在尝试使用kafka ruby客户端 - https://github.com/zendesk/ruby-kafka将日志发布到kafka。以下是kafka的日志

是否有任何人有关于如何修复它的任何信息。

Answer 1

我认为错误消息在您的情况下非常有用 - kafka2不可路由，因此您应该配置连接，以便您尝试访问kafka2的计算机真的可以访问它或者更改Kafka advertised.host.name中的server.properties以便为客户公开不同的地址

Answer 2

尝试在您的应用程序中ping {或{} kafka2代理，以查看您是否可以连接到它。或者你可以告诉我们关于server.properties的{{1}}。主机名可能无法访问。
