I would say divided nodes into 2 racks and update rack for each datanode from Ambari(configure rack topology). I don't have much insights on NodeGroup topology, are you referring to node labels? Please correct me if I'm wrong.

Looks like we currently don't have this in our docs yet. Per engineering, I will file a documentation bug. https://issues.apache.org/jira/browse/HDFS-6261

Hi, we have an official document for deploy HDP on VMs: https://hortonworks.com/wp-content/uploads/2014/02/1514.Deploying-Hortonworks-Data-Platform-VMware-vSphere-0402161.pdf. It has reference link on HVE (NodeGroup) feature which include details you may want to know.
