KafkaServerStable 启动期间 kafka 无法连接到 Zookeeper-FATAL 致命错误 [英] kafka cant connect to zookeeper- FATAL Fatal error during KafkaServerStable startup

问题描述

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

Well..every service in the world can connect to my zookeeper expect kafka. Below is my connection string in server.properties file

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..

Have have all ports on the two zookeeper servers ....total promiscuous mode. I can even telnet into the zookeeper server from the kafka server..

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?

So....rather confused on why kafka will not connect to zookeeper?

我使用的是 ubuntu 12.04 和 kafka 0.7.2

I am using ubuntu 12.04 and kafka 0.7.2

推荐答案

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

In your kafka/config/server.properties, there should be a property

#host.name=localhost

如果您取消了注释，或将其设置为其他名称，则该名称应在/etc/hosts 文件中

if you have uncommented this, or set this to another name, then that name should be in the /etc/hosts file
