How can I get more "real", but simulated Hadoop nodes for testing, without more machines? Can I add duplicate names in the slaves file? Or do I need separate IP's for everything?
This is just for testing purposes. Ideally, I'd like to simulate a few nodes on my Windows laptop, to make it easier to debug actual distributed stuff. Maybe if I am clever with Cygwin, I could get several sessions communicating with each other using virtual IP's, albeit all through localhost. But would I have issues with a single hadoop directory structure if I did this?
