01 發送消息 kafka版本： kafka_2.12-2.2.0
kafka 報錯信息
在kafka發送消息時的端口錯誤 導致 2181爲zookeeper配置的端口 而kafka配置的爲9092
[root@hdp bin]# ./kafka-console-producer.sh --broker-list 192.168.133.102:2181 --topic pro
具體報錯
[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.
更改爲
[root@hdp bin]# ./kafka-console-producer.sh --broker-list 192.168.133.102:9091 --topic pro
02 消費消息
[root@hdp bin]# ./kafka-console-consumer.sh --bootstrap-server 192.168.133.102:9092 --from-beginning --topic pro
hhh
