Question

我正在尝试使用Apache Kafka启动用户，它曾经运行良好，但是我必须格式化我的PC并再次重新安装所有内容，现在尝试运行此程序：

bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning

这就是我得到的：

                                          given to allow fail-over.

我的猜测是zookeeper连接端口存在某种问题，因为它告诉我指定Zookeeper连接到kafka所必须使用的端口。不过我不确定，也不知道如何找出端口来指定这是否是问题所在。有什么建议吗？

预先感谢您的帮助

您似乎正在使用旧版本的Kafka工具，如果要直接连接到代理，则需要设置--new-consumer。

我建议您选择最新版本的Kafka，因此您只需像示例中那样指定--bootstrap-server：http://kafka.apache.org/downloads

缺少必需的参数“ [zookeeper]”
