Subject Re: Connect a node in virtual machine with other nodes in physical machine with port forwarding
Date Sun, 06 Apr 2014 12:26:03 GMT

May I ask how you configured the VM? The hadoop on other machines can just
access the VM guest on another machine without port forwarding? (just
making sure I'm not being paranoid here :) )
