向 kafka 发送消息的时候出现 LeaderNotAvailableException 异常？

[alangz]

按照官网gettingStarted ->http://kafka.apache.org/documentation.html#gettingStarted ,我单独安装的zookeeper， 启动了三个boroker。创建了一个topic，按照官网的步骤发送消息的时候，总是出现LeaderNotAvailableException异常。

部分错误信息：

[2015-04-11 14:14:15,076] WARN Error while fetching metadata [{TopicMetadata for topic my-replicated-topic ->

在stackoverflow上面找到了一个类似的问题http://stackoverflow.com/questions/23228222/running-into-leadernotavailableexception-when-using-kafka-0-8-1-with-zookeeper-3 ，按照下面的回答说配置有问题，我停掉kafka和zookeeper清除掉kafka的log和zookeeper的内容。重新启动但还是有上述问题。

各位有遇到这个问题吗？

你的topic是咋创建的?

[alangz]

@lszwycn 按照官网的教程：
```
kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 3 --partitions 1 --topic my-replicated-topic
```

[lszwycn]

配置文件没改broker.id?

[alangz]

@lszwycn 改过了，按照他的文档一步一步做的

这个问题知道什么原因了，是因为主机名映射的ip错误，导致节点之间无法通信。
