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
>hello
[2019-08-16 09:00:09,767] ERROR Error when sending message to topic pro with key: null, value: 5 bytes with error: (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)
org.apache.kafka.common.errors.TimeoutException: Topic pro not present in metadata after 60000 ms.
更改为
[root@hdp bin]# ./kafka-console-producer.sh --broker-list 192.168.133.102:9091 --topic pro
02 消费消息
[root@hdp bin]# ./kafka-console-consumer.sh --bootstrap-server 192.168.133.102:9092 --from-beginning --topic pro
hhh
