1. 权限问题

Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): Permission denied: user=ASUS, access=WRITE, inode="/output":hadoop:supergroup:drwxr-xr-x

方法一：
在WordCountDriver.java上加入

System.setProperty("HADOOP_USER_NAME","root");

方法二：
给hadoop上增加权限

hadoop fs -chmod -R 777  

参考文章：
Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException):

Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException):

2. 确定对应版本的hadoop.dll和winutils.exe

Exception in thread “main” java.lang.UnsatisfiedLinkError: org.apache.hadoop.io.nativeio.NativeIO$Wi
