生产消息

打开消费控制台查看消息命令----- ./bin/kafka-console-consumer.sh --zookeeper zk1:2181 --topic test1 --from-beginning

出现下列错误信息：

[2016-03-09 13:51:02,016] WARN Fetching topic metadata with correlation id 955 for topics [Set(test3)] from broker [BrokerEndPoint(1,brk1,9092)] failed (kafka.client.ClientUtils$)

解决办法:

查看集群各个broker服务器是否打开了防火墙------/etc/rc.d/init.d/iptables status

查看结果有一台服务打开了防火墙  ，关闭   ----- /etc/rc.d/init.d/iptables stop
