1、启动生产者进程：

解决方法：
没有绑定Kafka启动监听的host信息
vi config/server.properties
-
listeners=PLAINTEXT://localhost:9092
2、使用API在开发时，启动报错

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=
注释去掉，并配置上kafka所在linux的ip地址。要和程序中的信息一致。要么都是IP,要么都是hostname
advertised.host.name=140.143.236.169
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:
192.168.10.10 kafka.host
Flume配置文件consumer.properties中
producer.sinks.r.brokerList = kafka.host:9092
