Scala for Apache Spark

The books is in the draft mode and I keep on updating it when I get time. This book does not 'teach' you Scala. This is a compilation of things / features / tips / tricks I learned along the way. Most of the book is full of code snippets with little or no explanation but if you know a liile bit of Scala or Spark the code snippets in this book will be handy.
