Hi Fabio,
I found this site extremely helpful in explaining how to do a one node setup
for a first time user:

You don't need 4 machines. You can put everything on a single machine. That
is the easiest to get started. Once you have a cluster running on a single
machine then you can spread out over multiple machines.
Best,

You can start with one machine or one VM if you are just looking to try out
hadoop.
