运行环境：windows10 64位，虚拟机：Ubuntu Kylin 14.04，Hadoop2.7.1
错误信息：
java.io.IOException: Could not locate executable D:\hadoop\bin\winutils.exe in the Hadoop binaries.
at org.apache.hadoop.util.Shell.getQualifiedBinPath(Shell.java:356)

解决办法：
下载winutils https://github.com/amihalik/hadoop-common-2.6.0-bin
将其解压到hadoop下
再配置环境变量，新建变量HADOOP_HOME，值为Hadoop目录，在PATH中添加%HADOOP_HOME%\bin（可能要重启）
OK。

Windows下运行MapReduce程序出现Could not locate executable null\winutils.exe in the Hadoop binaries.
