The easiest way to get set up with a Hadoop sandbox I've ever seen is the HortonWorks Data Platform sandbox VM. Use that to get up to speed instead of rolling your own. It comes with Hadoop, HBase, Spark and a bunch of other stuff ready to go with minimal fuss and is designed to be used to support development on your workstation from the guest OS.
