cm管理hadoop集羣hdfs切換用戶

使用CDH和CM管理hadoop集羣切換用戶

CDH和CM管理hadoop集羣后，創建很多用戶hdfs、hive、hue等等，上傳文件到hdfs發現登陸不了hdfs用戶。

[root@node01 localData]# su - hdfs
This account is currently not available.

查看hdfs的帳號信息

[root@node01 localData]# cat /etc/passwd|grep hdfs
hdfs:x:985:978:Hadoop HDFS:/var/lib/hadoop-hdfs:/sbin/nologin

發現它的shell是“/sbin /nologin”，需要將其改成“/bin/bash”

[root@node01 localData]# vim /etc/passwd

保存退出，su - hdfs試試。

[root@node01 localData]# su hdfs -c "hadoop dfs -mkdir /user/root"
WARNING: Use of this script to execute dfs is deprecated.
WARNING: Attempting to execute replacement "hdfs dfs" instead.

[root@node01 localData]# su hdfs -c "hadoop dfs -ls /user"
WARNING: Use of this script to execute dfs is deprecated.
