Kafka Zookeeper连接问题

我正在使用Kafka 0.8.2-beta并拥有2个Ubuntu 14虚拟机：

• 172.30.141.127正在运行Zookeeper

• 172.30.141.184正在运行Kafka经纪人

我正在启动Zookeeper实例，一切都很好 . 然后我尝试启动代理并将其连接到172.30.141.127:2181 . 它似乎能够在特定端口上连接并 Build 会话，但由于某些异常似乎没有记录，它会丢失连接 .

经纪人输出：

Ping在两台机器之间工作 . Telnet到2181种工作，因为它连接，但不时断开连接 . 这让我认为问题出在Zookeeper实例上 . 这两个进程都以root身份启动 .

任何想法为什么会这样？谢谢
