Question

嗯..世界上的每一项服务都可以连接到我的动物园管理员，期待kafka。下面是我在server.properties文件中的连接字符串

zk.connect=1.dzk.syd.druid.neo.com:2181, 2.dzk.syd.druid.neo.com:2181

两个zookeeper服务器上都有所有端口....总混杂模式。我甚至可以从kafka服务器telnet到zookeeper服务器..

telnet  2.dzk.syd.druid.neo.com 2181
Trying 54.252.183.218...
Connected to 2.dzk.syd.druid.neo.com.
Escape character is '^]'.

所以......为什么kafka不会连接到zookeeper而感到困惑？

我使用的是ubuntu 12.04和kafka 0.7.2

Answer 1

在你的kafka / config / server.properties中，应该有一个属性

#host.name=localhost

如果您已取消注释，或将其设置为其他名称，则该名称应位于/ etc / hosts文件中

Answer 2

已经回答了好一阵子了，但是如果可以帮助某人，这就是我的解决方法：

实际上，我正在使用Ansible剧本安装Kafka集群，并且zookeeper.properties文件中生成的参数未正确排序：

server.1=0.0.0.0:2888:3888
server.2=kafka-4:2888:3888
server.3=kafka-5:2888:3888
server.4=kafka-3:2888:3888
server.5=kafka-2:2888:3888

以正确的顺序放置它们，

server.1=0.0.0.0:2888:3888
server.2=kafka-2:2888:3888
server.3=kafka-3:2888:3888
server.4=kafka-4:2888:3888
server.5=kafka-5:2888:3888

然后重新启动Kafka服务，对其进行修复。

kafka无法连接到zookeeper-FATAL KafkaServerStable启动期间的致命错误
