kafka生产消费失败的原因

kafka生产消费时报错如下：

定位问题的原因是：

server.properties:advertised.listeners=PLAINTEXT://10.1.4.1:9092   ---该ip不能被写死
不该被写死IP信息：
再写入新的配置项：
server.properties:
delete.topic.enable=true

有时候是因为：

./bin/kafka-console-consumer --zookeeper DCP185:2181,DCP186:2181,DCP187:2181/kafka --from-beginning --topic wangjuan_topic1 --new-consumer --consumer.config ./etc/kafka/consumer.properties --bootstrap-server DCP187:9092

解决方法：配置文件中下面的参数中的User的U必须是大写；
super.users=User:kafka


或者有可能是server.properties中的adver.listen的IP是不对的，有可能是代码中写死的IP；
