Install Options

In order to create the cluster, the Cluster Setup Wizard asks you for general information about how you want to configure it. You must provide the FQDN of each of your hosts. The wizard also needs access to the private key file that you created when setting up passwordless SSH. Using hostnames and key file information, the wizard can securely locate, access, and interact with all hosts in the cluster.

1. In Target Hosts, enter your list of hostnames, one per line. You can use ranges in parentheses to indicate larger sets of hosts. For example, for host01.mycluster.clemlab.local to host10.mycluster.clemlab.local, use host[01-10].mycluster.clemlab.local.
2. If you want to let Ambari automatically install the Ambari agent on all your hosts using SSH, select Provide your SSH Private Key and use the Choose File button in the Host Registration Information section to find the private key file that corresponds to the public key you installed. earlier on all your hosts or manually cut and paste the key into the text box.
3. Enter the username for the SSH key you selected. If you do not want to use root, you must provide the username of an account that can run sudo without entering a password. If SSH on the hosts in your environment is configured for a port other than 22, you can change that too.
4. If you do not want Ambari to automatically install Ambari agents, select Perform manual registration.
5. Choose Register and Confirm to continue.
