Permission denied: user=xxj, access=WRITE, inode="user":hadoop:supergroup:rwxr-xr-x

在windows中运行eclipse时报错Permission denied: user=xxj, access=WRITE, inode="user":hadoop:supergroup:rwxr-xr-x，是因为运行时的用户为为administrator，只需要在eclipse中将用户改为Hadoop的用户即可 run as----run configuration  里面的vm argument -DHADOOP-USER-NAME=hadoop
