【问题】Failed to send producer request with correlation id 2 to broker 0 with

部署Flume在Window环境中，Kafka部署在Linux上，从Flume发送事件到Kafka始终有一下错误，

经过长时间在网上搜索终于把问题解决，

解决办法1：

修改kafka中配置项，

#advertised.host.name=<hostname routable by clients>

注释去掉，并配置上kafka所在linux的ip地址

advertised.host.name=192.168.10.10

重启kafka。

解决办法2（推荐）：

将kafka所在linux的（ip，别名）配置到Window环境中hosts文件:

Flume配置文件consumer.properties中
