ACKNOWLEDGMENTS

TO THE MANY PEOPLE that I have worked with. They always have been pushing me to the limit, questioning my solutions, and consequently making them better. A lot of their ideas are used in this book, and hopefully made the book better.

Many thanks to Dean Wampler, who has contributed Hadoop domain-specific languages content for Chapter 13.

To my co-authors, Kevin and Alexey, who brought their own perspective on Hadoop to the book’s coverage, and made it better and more balanced.

To the technical editors for many valuable suggestions on the book’s content.

To the Wiley editorial staff — Bob Elliott, for deciding to publish this book; our editor, Kevin Shafer, for relentlessly working to fix any inconsistencies; and many others, for creating the final product that you are reading.

FIRST OF ALL, I would like to thank my co-authors and the great team at Wrox Press for this effort. As this is my seventh book project, I would like to especially thank my wonderful wife, Gwen, and my sweet children, Isabella, Emma, and Henry, for putting up with the long days, nights, and weekends where I was camped out in front of my computer.

A sincere thanks to the many people who read the early drafts of these chapters, and provided comments, edits, insights, and ideas — specifically Mike Daconta, Ralph Perko, Praveena Raavichara, Frank Tyler, and Brian Uri. I am grateful to my company, Novetta Solutions, and I would especially like to thank Joe Pantella and the rest of the Novetta executive team for being supportive of me in writing this book.

There were several things that could have interfered with my book writing this year. For a while, the Washington Redskins seemed unstoppable, and if they had actually made it to the Super Bowl, this would have put my book deadlines in jeopardy. However, the Redskins’ season and another season that I was involved in were abruptly brought to an end. Therefore, we have the Redskins and the POJ to thank for the timeliness of this book.

Finally, special thanks to CiR, Manera, and the One who was, is, and is to come.

— Kevin T. Smith

TO MY COLLEAGUES at Nokia, where I was working while writing the book, and whose advice and knowledge created the highly professional context for my chapters.

To my co-authors, Boris and Kevin, who made this book and my participation possible.

To the Wiley editorial staff, for publishing the book, and for providing all the necessary help and guidance to make the book better.
