The username is changed to maria_dev, and also I can't find the admin tab for enable kerberos. Is there any way to get the admin permission to enable kerberos ?
The user behavior in the sandbox was changed due to security considerations. User maria_dev is the default user for running tutorials and is read-only ( cannot affect services in ambari ).
The admin user is still present however the password has changed and needs to be reset from inside the sandbox VM by using the #ambari-admin-password-reset command.

You will have to login as admin in Ambari, then click on Admin > Kerberos.
Default username is admin and default password is also admin for Ambari UI
Thank you for this information
You can also go to the Sandbox splash screen localhost:8888. And then click on the advance button and it will also provide an outline on how the process to update the Ambari admin id.
There is also a intro to the sandbox tutorial called Learning the ropes
This also walks you through the process of updating the Ambari Admin pwd.
The easiest way to do it:
Just log in to the Ambari using these credentials:
