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.

Summary

In this chapter, we had a brief introduction to the topic and got a grasp of simple, yet powerful and common ML techniques. Finally, you saw how to build your own predictive model using Spark. You learned how to build a classification model, how to use the model to make predictions, and finally, how to use common ML techniques such as dimensionality reduction and One-Hot Encoding.

In the later sections, you saw how to apply the regression technique to high-dimensional datasets. Then, you saw how to apply a binary and multiclass classification algorithm for predictive analytics. Finally, you saw how to achieve outstanding classification accuracy using a random forest algorithm. However, we have other topics in machine learning that need to be covered too, for example, recommendation systems and model tuning for even more stable performance before you finally deploy the...
