我确实设置了 hadoop Ubuntu 操作系统，遵循了所有必要的步骤，1.创建了 hdfs 文件系统 2.将文本文件移动到输入目录 3.具有访问所有目录的权限。但是当运行简单的字数统计示例时，我得到了

For hadoop-2.2.0 on windows 7, I added the below lines and it solved the issue (NOTE: My Hadoop Home is: C:\MyWork\MyProjects\Hadoop\hadoop-2.2.0)
对于 windows 7 上的 hadoop-2.2.0，我添加了以下几行并解决了问题（注意：我的 Hadoop 主页是：C:\MyWork\MyProjects\Hadoop\hadoop-2.2.0）
Configuration conf = new Configuration();
配置 conf = 新配置（）；
conf.addResource(new Path("C:\MyWork\MyProjects\Hadoop\hadoop-2.2.0\etc\hadoop\core-site.xml"));
conf.addResource(new Path("C:\MyWork\MyProjects\Hadoop\hadoop-2.2.0\etc\hadoop\core-site.xml"));
conf.addResource(new Path("C:\MyWork\MyProjects\Hadoop\hadoop-2.2.0\etc\hadoop\hdfs-site.xml"));
conf.addResource(new Path("C:\MyWork\MyProjects\Hadoop\hadoop-2.2.0\etc\hadoop\hdfs-site.xml"));
