Acknowledgments

While writing this book, I received help (both directly and indirectly) from a lot of people, and I would like to thank them all. Thanks to the Hadoop community and the user forums, from whom I have learned a great deal. There are many selfless people in the Hadoop community, and I feel that’s the biggest strength of the “Hadoop revolution.” In particular, thanks to my friend Satya Kondapalli for introducing Hadoop to me, and to my friends Naveed Asem and Zafar Ahmed for keeping me motivated!

I would like to thank the Intel Technical team (Bala Subramanian, Sunjay Karan, Manjunatha Prabhu) in Chicago for their help with Intel’s Hadoop distribution and encryption at rest, as well as Cloudera’s Justin Kestelyn for providing information about Sentry. Last, I would like to thank my friend Milind Bhandarkar (of Pivotal) for his help and support.

I am grateful to my editors, Linda Laflamme and Rita Fernando, at Apress for their help in getting this book together. Linda and Rita have been there throughout to answer any questions that I have, to read and improve my first (and second and third . . .) drafts, and to keep me on schedule! I am also very thankful to Robert Geiger for taking time to review my book technically. Bob always had great suggestions for improving a topic, recommended additional details, and, of course, resolved technical shortcomings!

Last, writing this book has been a lot of work, and I couldn’t have done it without the constant support from my family. My wife, Swati, and my kids, Anish and Riya, have been very understanding. I’m looking forward to spending lots more time with all of them!
