二、错误原因分析
报错信息简单明了：与主机绑定失败。首先想到的就是是不是端口被占用了，使用 netstat -anp|grep 命令查了并没有被占用，换了个端口重启程序，还是报同样的错误。看来这个错误不是端口被占用了这么简单。
就当快要放弃的时候，突然想到了官方文档，于是打开了下面的链接，希望能有所发现。
https://spark.apache.org/docs/1.6.2/streaming-flume-integration.html
就是红色下划线那句话，引起了我的注意：
When your Flume + Spark Streaming application is launched, one of the Spark workers must run on that machine.
本机调试使用的是Windows电脑，但是绑定的主机确实服务器上的ip和port，根本就不是在一个机器上，除非使用spark-submit在服务器上提交作业才行。
三、解决方案
本机调试阶段，把程序的传入参数改了：
这样就可以了。

ps: 使用flume的pull模式可以指定服务器（非本机）
