个人博客地址：org.apache.kafka.common.errors.TimeoutException | 一张假钞的真实世界

使用kafka-console-producer.sh向远端Kafka写入数据时遇到以下错误：

$ bin/kafka-console-producer.sh --broker-list 172.16.72.202:9092 --topic test
This is a message

在没有配置advertised.host.name的情况下，Kafka并没有广播我们配置的host.name，而是广播了主机配置的hostname。远端的客户端并没有配置hosts，所以自然是连接不上这个hostname的，所以在远端客户端配置hosts。在客户端/etc/hosts中添加以下内容后问题解决：
