7. Admin View

The Admin view allows you to manage users, to add them, make them administrators, delete them, or change their passwords. There are two user roles: User and Admin. Users can view metrics, view service status and configuration, and browse job information. Admins can do all User tasks and in addition can start or stop services, modify configurations, and run smoke tests.

To make a change in a current user's password, click edit, in red above. To add an additional user, click +Add Local User. In both cases, a variant of the username pop up appears.

For a new user, enter the desired Username and Password. Check Admin to make this user an administrator. For an existing user, enter the old and new Passwords. Make your changes and click Save.

To check the service user accounts that have been assigned to various Hadoop services, click the Misc tab.
