FAQ
I'm installing and managing Cloudera Manager with Chef and the CM API.
However, we need to be able to secure the cluster beyond the default
admin:admin username and password. Is there any programmatic way,
preferably with the API or a config file, to change the default
username/password?

Thanks,
Tejay Cardon

    Hi Tejay,

    The API has had support for updating user information since the first
    version. Check out the documentation:
    http://cloudera.github.io/cm_api/apidocs/v1/path__users_-userName-.html#PUT


    Any user can update their own password, so you should be able to
    update the admin's password by using the default admin/admin
    credentials to make the API call.

    Ok, that would let me update the admin user's password. It would also let
    me create a new user and give that user admin credentials. What would
    happen if I then removed the admin user? Is that supported by CM, or does
    the admin user have to continue to live?

    Users are not allowed to delete themselves, but if you create a second
    admin user as you say, you should be able to use it to delete the
    default "admin" user.
