Click Show Cluster Template on the Actions menu to review the template used in cluster creation. Click Show CLI Command to review the CDP CLI command used to create the cluster (which you can copy to create similar clusters via the CDP CLI). Select Manage Access to manage access to the cluster.
You can also perform some basic Data Hub management functions from the Actions menu, such as resizing, retrying, and repairing the cluster, as well renewing the host certificate.
