 An introduction to the subject can be found in the best known reference :

Hadoop: The Definitive Guide, 3rd Edition

Chapter 6 How MapReduce Works -> Shuffle and Sort -> around page 208

After reading this, you should have a good understanding of the
architecture and know that indeed there is no "shuffle phase replication
factor" (cf your question on another thread). For the technical details,
the code is probably the next step.
