kafka.common.KafkaException: fetching topic metadata for topics [Set(topic1)] from broker [ArrayBuffer(id:0,host:localhost,port:9092)] failed

原因：是在集群环境里执行了单机的命令

解决方法：

1)vi producer.properties

#metadata.broker.list=localhost:9092

metadata.broker.list=192.168.11.222:9092,192.168.11.221:9092,192.168.11.220:9092

2)./kafka-console-producer.sh --broker-list IP1:9092,IP2:9092,IP3:9092 --topic topic1
