After completing the Add Cluster - Installation wizard, the Add Cluster - Configuration wizard automatically starts. The following sections guide you through each page of the wizard:

To include Cloudera Navigator data management, check the box labeled Include Cloudera Navigator.
After selecting the services you want to add, click Continue. The Assign Roles page displays.
Assign Roles
The Assign Roles page suggests role assignments for the hosts in your cluster. You can click on the hostname for a role to select a different host. You can also click the View By Host button to see all the roles assigned to a host.
To review the recommended role assignments, see Recommended Cluster Hosts and Role Distribution.
After assigning all of the roles for your services, click Continue. The Setup Database page displays.
Setup Database
On the Setup Database page, you can enter the database hosts, names, usernames, and passwords you created in Step 4: Install and Configure Databases. For services that support it, you can add finer-grained customizations using a JDBC URL override.
Select the database type and enter the database name, username, and password for each service. For MariaDB, select MySQL.
For services that support it, to specify a JDBC URL override, select Yes in the Use JDBC URL Override dropdown menu. For information on the JDBC URL format, see Specifying a JDBC URL Override for Database Connections. You must also specify the database type, username, and password.
Click Test Connection to validate the settings. If the connection is successful, a green checkmark and the word Successful appears next to each service. If there are any problems, the error is reported next to the service that failed to connect.
After verifying that each connection is successful, click Continue. The Review Changes page displays.
Review Changes
The Review Changes page lists default and suggested settings for several configuration parameters, including data directories.
Review and make any necessary changes, and then click Continue. The Command Details page displays.
If you are installing the Accumulo Service, select Initialize Accumulo to initialize the service as part of the installation process.
Command Details
The Command Details page lists the details of the First Run command. You can expand the running commands to view the details of any step, including log files and command output. You can filter the view by selecting Show All Steps, Show Only Failed Steps, or Show Only Running Steps.
After the First Run command completes, click Continue to go to the Summary page.
Summary
The Summary page reports the success or failure of the setup wizard. Click Finish to complete the wizard. The installation is complete.
Cloudera recommends that you change the default password as soon as possible by clicking the logged-in username at the top right of the home screen and clicking Change Password.
