Adding a Cluster Using New Hosts
Use the Add Cluster - Installation wizard to create a regular or computer cluster using new hosts.
On the Cloudera Manager Home page, click the Add drop-down button at the top right, or the Clusters drop-down button at the top left, and then click Add Cluster. This launches the Add Cluster - Installation wizard, which allows you to create either a regular cluster or a compute cluster.
You can also launch the wizard by selecting Add Compute Cluster from the drop-down menu next to the cluster name. Launching the wizard from there skips the Welcome page and restricts the wizard to creating only a compute cluster.
