apache-zookeeper - KafkaServerStable 启动期间 kafka 无法连接到 Zookeeper-FATAL fatal error

Question

嗯..世界上的每个服务都可以连接到我的动物园管理员，除了 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

在两个zookeeper服务器上拥有所有端口......完全混杂模式。我什至可以从 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....对为什么 kafka 无法连接到 zookeeper 感到困惑？

我正在使用 ubuntu 12.04 和 kafka 0.7.2

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，则该名称应在/etc/hosts 文件中
