问题描述
好吧..世界上的每一个服务都可以连接到我的动物园管理员卡夫卡.以下是我在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服务器上都具有所有端口....总混杂模式.我什至可以从kafka服务器远程登录到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....让kafka为什么无法连接到zookeeper还是很困惑?
So....rather confused on why kafka will not connect to zookeeper?
我正在使用ubuntu 12.04和kafka 0.7.2

推荐答案
在您的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
如果您未对此进行注释，或将其设置为其他名称，则该名称应位于/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
