Exception in thread "main" java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO$Windows.access0(Ljava/lang/String;I)Z

　　该错误和我的上一篇博文ERROR [org.apache.hadoop.util.Shell] - Failed to locate the winutils binary in the hadoop binary path一样是由于缺少文件引起的，错误日志如下：

　　解决方法是下载https://github.com/srccodes/hadoop-common-2.2.0-bin文件然后将其中的hadoop.dll文件放到hadoop安装路径的bin文件夹下（配置好HADOOP_HOME的环境变量），然后重启电脑，这样问题就能得到解决了！
