Scala and Spark for Big Data Analytics

By: Md. Rezaul Karim, Sridhar Alla

Overview of this book

Scala has been observing wide adoption over the past few years, especially in the field of data science and analytics. Spark, built on Scala, has gained a lot of recognition and is being used widely in productions. Thus, if you want to leverage the power of Scala and Spark to make sense of big data, this book is for you. The first part introduces you to Scala, helping you understand the object-oriented and functional programming concepts needed for Spark application development. It then moves on to Spark to cover the basic abstractions using RDD and DataFrame. This will help you develop scalable and fault-tolerant streaming applications by analyzing structured and unstructured data using SparkSQL, GraphX, and Spark structured streaming. Finally, the book moves on to some advanced topics, such as monitoring, configuration, debugging, testing, and deployment. You will also learn how to develop Spark applications using SparkR and PySpark APIs, interactive data analytics using Zeppelin, and in-memory data processing with Alluxio. By the end of this book, you will have a thorough understanding of Spark, and you will be able to perform full-stack data analytics with a feel that no amount of data is too big.

SBT and other build systems

It's necessary to use a build tool for any enterprise software project. There are lots of build tools that you can choose from, such as Maven, Gradle, Ant, and SBT. A good choice of build tool is the one which will let you focus on coding rather than compilation complexities.

Build with SBT

Here, we are going to give a brief introduction to SBT. Before going any further, you need to install SBT using the installation method that fits your system from their official installations methods (URL: http://www.scala-sbt.org/release/docs/Setup.html).

So, let's begin with SBT to demonstrate the use of SBT in a terminal. For this build tool tutorial, we assume that your source code files are in...
