How to set hadoop network configuration properties when there are two network interfaces, public/private?

I'm setting up a hadoop cluster where each of the nodes is connected to the public network as well as a private dedicated network for the cluster.  I want most of the communication between nodes to happen on the private network and for data moving into and out of the cluster (sqoop tasks, etc.)  on the public network. Should I put the public or private hostname for the following properties.


If I should put the private hostname, is it ok that the hostname command returns the public hostname?
