If you want a free O.S , ubuntu is good but if you are familia= r with RedHat then you may want to have look at Scientific Linux (Its free = as well)

If= you got a laptop with you then thats all you need to learn hadoop. Hadoop = can be installed in a pseudo distributed mode on a single machine and you c= an use it with localhost all the time.
