我是靠谱客的博主 欢喜含羞草，最近开发中收集的这篇文章主要介绍WARN [Producer clientId=console-producer] Connection to node -1 could not be established. Broker ...，觉得挺不错的，现在分享给大家，希望可以做个参考。
概述
测试向kafka中发消息
unset JMX_PORT; bin/kafka-console-producer.sh
--broker-list localhost:9092
--topic test-topic
然后随便输入数据, 回车, 报错:
WARN [Producer clientId=console-producer] Connection to node -1 could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)
实际上是地址的问题, 改成下面的就可以了(实际地址取决于你的kafka配置)
unset JMX_PORT; bin/kafka-console-producer.sh
--broker-list PLAINTEXT://192.168.3.125:9092
--topic test-topic
实际中应该看自己kafka的配置(默认是:${KAFKA_ROOT}/config/server.properties)
(完)
最后
以上就是欢喜含羞草为你收集整理的WARN [Producer clientId=console-producer] Connection to node -1 could not be established. Broker ...的全部内容，希望文章能够帮你解决WARN [Producer clientId=console-producer] Connection to node -1 could not be established. Broker ...所遇到的程序开发问题。
