需要先在linux 上創建一個普通用戶： hadoop-cw,並修改密碼
[root@cm1 ~]# useradd hadoop-cw
[root@cm1 ~]# passwd hadoop-cw
Changing password for user hadoop-cw.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
然后在hdfs上/user目錄下創建用戶目錄
[root@cm1 ~]# sudo -u hdfs hdfs dfs -mkdir /user/hadoop-cw
[root@cm1 ~]# hdfs dfs -ls /user
Found 7 items
