Preface

This book will take you on a hands-on exploration of the wonderful world that is Hadoop 2 and its rapidly growing ecosystem. Building on the solid foundation from the earlier versions of the platform, Hadoop 2 allows multiple data processing frameworks to be executed on a single Hadoop cluster.

To give an understanding of this significant evolution, we will explore both how these new models work and also show their applications in processing large data volumes with batch, iterative, and near-real-time algorithms.
