Spark/Hadoop开发缺失插件-winutils.exe

本地开发Spark/Hadoop报错“ERROR Shell: 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.” 缺少Hadoop插件winutils.exe所致。 两种解决方案： 1、下载该文件到D:\hadoop\bin下，并设置环境变量HADOOP_HOME：D:\hadoop； 2、下载该文件到D:\hadoop\bin下，并在代码中设置System.setProperty("hadoop.home.dir","D:\\hadoop")；
