apache-zookeeper – kafka无法连接到zookeeper-FATAL在KafkaServerStable启动期间出现致命错误

嗯..世界上的每一项服务都可以连接到我的动物园管理员,期待卡夫卡.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

在两个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……相当困惑为什么kafka不会连接到zookeeper?

我使用的是ubuntu 12.04和kafka 0.7.2

最佳答案
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
