A Step Up from the Hadoop documentation,
Verified Purchase(What is this?)
This review is from: Hadoop: The Definitive Guide (Paperback)
This book is well organized and spans the Hadoop stack. As a relative newcomer to Hadoop, I'd already read many of the online docs and surveyed some of the source code, but having this book clarified some issues and questions that had arisen. It's a useful reference if you are working with Hadoop or interested in the Hadoop stack.
