一旦我尝试在我的多节点多厂商kafka集群中生成消息，我就会收到以下错误并且无法生成消息。我能够正确列出和描述主题。 

 bin/kafka-console-producer.sh --broker-list localhost:9092 --topic nil_RF2_P1

你好了解决方案。

我必须更改多节点多代理kafka集群的producer.properties文件，其中包含以下内容：

metadata.broker.list=2:172.16.30.4:9092,4:172.16.30.4:9093,1:172.16.30.5:9092,3:172.16.30.5:9093

Explanation:
We have 2 nodes
172.16.30.4
172.16.30.5

with 2 brokers running in ports 
9092
9093

The preceeding integer in each ip is the myid of the zookeeper, while successing integer is port!!

希望它会对某人有所帮助。
