I would like to thank my wife, Smita and son, Aryan for their sacrifices and support during this journey, and my dad, mom, and sister for encouraging me at all times to make a difference by contributing back to the community. This book would not have been possible without their encouragement and constant support.

Special thanks to Rupak and Debika for investing their personal time over weekends to help me experiment with a few ideas on Hadoop security, and for being the bouncing board.

I would like to thank Shwetha, Sivaram, Ajay, Manpreet, and Venky for providing constant feedback and helping me make continuous improvements in my securing Hadoop journey.

Above all, I would like to acknowledge my sincere thanks to my teacher, Prof. N. C. Jain; my leaders and coach Paddy, Vishnu Bhat, Sandeep Bhagat, Jaikrishnan, Anil D'Souza, and KNM Rao for their mentoring and guidance in making me who I am today, so that I could write this book.
