An introduction to the subject can be found in the best known reference : Hadoop: The Definitive Guide, 3rd Edition Storage and Analysis at Internet Scale By Tom White <http://shop.oreilly.com/product/0636920021773.do#tab_04> Publisher: O'Reilly Media / Yahoo Press Released: May 2012

For the technical details, the code is probably the next step.
