Hi visioner,
It won't work on pseudo distributed because you need to run at least 2 NN and if you run 2NN then u need to configure them separately on different ports. It's little tricky doing on one node. Multiple VM is the cleanest solution.

I have a single linux node in which i installed 0.23.3 in pseudo-mode can i test federation configuration and functionality using this or will i have to install hadoop in a cluster with atleast 3 linux nodes ......incase of my single linux box i have 3 ips with me.....
