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

部署Flume在Window環境中，Kafka部署在Linux上，從Flume發送事件到Kafka始終有一下錯誤，

經過長時間在網上搜索終于把問題解決，

解決辦法1：

修改kafka中配置項，

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

注釋去掉，并配置上kafka所在linux的ip地址

advertised.host.name=192.168.10.10

重啟kafka。

解決辦法2（推薦）：

將kafka所在linux的（ip，別名）配置到Window環境中hosts文件:

192.168.10.10  kafka.host

Flume配置文件consumer.properties中

producer.sinks.r.brokerList = kafka.host:9092
