does vertica have a guide to extend single node to cluster?

    It depends if how you have installed vertica at first. You can add nodes to single node cluster if you have done installation using -s option.

    # /opt/vertica/sbin/install_vertica -s host_list -r rpm_package -u dba_username

    -s host_list
    A comma-separated list of hostnames or IP addresses to include in the cluster; do not include space characters in the list. 

    -s host01,host02,host03

    This parameter is required on multi-node installations. 

    On single-node installations the parameter is optional and the default is localhost. 

    If you plan to expand to additional hosts later, then you must use the -s parameter. Installations done without the -s parameter cannot 
    be upgraded to a multiple-node deployment, and must be re installed to support additional nodes.

    Note: If you are upgrading an existing installation of HP Vertica, specify one hostname, and HP Vertica finds the rest of the nodes.

    You can get guidelines how to install vertica & add hosts on below links:
