@Marcy

All Service accounts i.e. hive, hdfs, mapred etc. are kind of password-less with auto generated and auto changed hash passwords i.e. managed accounts. You can login to these users from a sudo user account or as root user by doing "su - hive" or "sudo su - hive" and so on based on root or sudo user account.

[root@sandbox ~]# su - hive
[hive@sandbox ~]$ 
[hive@sandbox ~]$ whoami
hive
