报错：`zookeeper is not a recognized option`和disconnected (org.apache.kafka.clients.NetworkClient)

报错zookeeper is not a recognized option

[root@localhost bin]# ./kafka-console-consumer.sh --zookeeper localhost:2181 --from-beginning --topic userlog
zookeeper is not a recognized option
Option                                   Description                            
------                                   -----------                            

原因为： 当前使用的 创建消费者命令 与 安装的kafka版本不一致，因为kafka在0.9版本之后，使用创建的kafka 消费者命令已经变了。
应该将上面的命令变为下面的命令进行运行
--zookeeper修改为--bootstrap-server

新版本不适用端口2181，而是9092
应该修改为下面的命令

[root@localhost bin]# ./kafka-console-consumer.sh --bootstrap-server localhost:9092 --from-beginning --topic userlog
