kafka使用常见报错及解决方法

参考技术A server.properties中有两个listeners。 listeners：启动kafka服务监听的ip和端口，可以监听内网ip和0.0.0.0(不能为外网ip)，默认为java.net.InetAddress.getCanonicalHostName()获取的ip。advertised.listeners：生产者和消费者连接的地址，kafka会把该地址注册到zookeeper中，所以只能为除0.0.0.0之外的合法ip或域名 ，默认和listeners的配置一致。

只有在jdk1.9并且kafka版本在1.0.x之前的版本才会出现。
