ERROR Error when sending message to topic pro with key: null, value: 5 bytes with error

01 发送消息   kafka版本：  kafka_2.12-2.2.0

kafka 报错信息

在kafka发送消息时的端口错误 导致 2181为zookeeper配置的端口  而kafka配置的为9092

[root@hdp bin]# ./kafka-console-producer.sh --broker-list 192.168.133.102:2181 --topic pro

具体报错

[root@hdp bin]# ./kafka-console-producer.sh --broker-list 192.168.133.102:2181 --topic pro
