To add new hosts to your cluster, browse to the Hosts page and select +Add New Hosts, from the Actions menu. The Add Host Wizard provides a sequence of prompts similar to those in the Ambari Install Wizard. Follow the prompts, providing information simliar to that provided to define the first set of hosts in your cluster.
To review the Ambari Install Wizard procedure, see Installing, Configuring, and Deploying the Cluster in the Ambari Installation Guide.
