Preface > Intended Audience

Intended Audience

The motivation for us to write this book was to fill a missing gap we saw in a lot of new MapReduce developers. They had learned how to use the system, got comfortable with writing MapReduce, but were lacking the experience to understand how to do things right or well. The intent of this book is to prevent you from having to make some of your own mistakes by educating you on how experts have figured out how to solve problems with MapReduce. So, in some ways, this book can be viewed as an intermediate or advanced MapReduce developer resource, but we think early beginners and gurus will find use out of it.

This book is also intended for anyone wanting to learn more about the MapReduce paradigm. The book goes deeply into the technical side of MapReduce with code examples and detailed explanations of the inner workings of a MapReduce system, which will help software engineers develop MapReduce analytics. However, quite a bit of time is spent discussing the motivation of some patterns and the common use cases for these patterns, which could be interesting to someone who just wants to know what a system like Hadoop can do.
