Select Users in the left nav bar to add Ambari Web users, 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 Ambari Web user, click +Add Local User. In both cases, a variant of the username pop up appears.
For a new Ambari Web user, enter the desired Username and Password. Check Admin to make this user an administrator. Click Create to make the user.
For an Ambari Web existing user, enter the old and new Passwords. Make your changes and click Save.
To delete an existing Ambari Web user, click delete and fill in the Username.
