[大数据]运行MapReduce程序出现org.apache.hadoop.io.nativeio.NativeIO$POSIX.stat(Ljava/lang/String

当运行MapReduce程序时出现如下错误：

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO$POSIX.stat(Ljava/lang/String;)Lorg/apache/hadoop/io/nativeio/NativeIO$POSIX$Stat;

主要原因是 你的输入路径是文件夹，不是文件

解决方法：
比如你的路径为： D:\input
如果你想要计算input下的文件，就必须加个 “*”，否则会报如上的错

正确写法： D:\input\*
