Description

/data   <dir>           2008-04-04 00:47        rwxr-xr-x       root   users
/data/testdir   <dir>           2008-04-04 23:44        rwxrwxrwx       knoguchi        users
/user/knoguchi/test     <dir>           2008-04-04 23:45        rwxrwxrwx       knoguchi        users

[knoguchi]$  hadoop dfs -mv /user/knoguchi/test /data/testdir
mv: org.apache.hadoop.fs.permission.AccessControlException: Permission denied: user=knoguchi, access=WRITE, inode="data":root:users:rwxr-xr-x

Since target directory, /data/testdir, exists, it should not check the permission of the parent directory
