About the Author

Antonios Chalkiopoulos is a developer living in London and a professional working with Hadoop and Big Data technologies. He completed a number of complex MapReduce applications in Scalding into 40-plus production nodes HDFS Cluster. He is a contributor to Scalding and other open source projects, and he is interested in cloud technologies, NoSQL databases, distributed real-time computation systems, and machine learning.

He was involved in a number of Big Data projects before discovering Scala and Scalding. Most of the content of this book comes from his experience and knowledge accumulated while working with a great team of engineers.

I would like to thank Rajah Chandan for introducing Scalding to the team and being the author of SpyGlass and Stefano Galarraga for co-authoring chapters 5 and 6 and being the author of ScaldingUnit. Both these libraries are presented in this book.

Saad, Gracia, Deepak, and Tamas, I've learned a lot working next to you all, and this book wouldn't be possible without all your discoveries. Finally, I would like to thank Christina for bearing with my writing sessions and supporting all my endeavors.
