spark单机环境下运行一些解决问题

1. ERROR1、hadoop依赖

   [ERROR] - Failed to locate the winutils binary in the hadoop binary path
   java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries.

解决办法：

1) 下载所需的winutils.exe

2)存放至一个路径如——d:\winutil\bin

3)文件中加入System.setProperty("hadoop.home.dir", "d:\\winutil\\")

2.ERROR2、端口冲突
java.net.BindException: Address already in use: Cannot bind
解决办法：打开任务处理器，关闭java进程

  3.ERROR3、主机未设定
 A master URL must be set in your configuration
解决办法：
代码中：val conf = new SparkConf().setAppName("Word Test")
改成：val conf = new SparkConf().setMaster("local[*]").setAppName("Word Test")
