Subject Re: How to run two data nodes on one pc?

You can run in Standalone mode following the quickstart instructions 
(google hadoop standalone or hbase standalone).  The other option is 
pseudo-distributed mode where it's the same OS uses a different JavaVM.

I agree with Marcos, either you need a commercial virtualization layer 
that lets you run double kernels natively (which on a Duo core--which I 
doubt has the memory--won't really be that useful) or VMware.
