Overview of this book

Big Data Analytics book aims at providing the fundamentals of Apache Spark and Hadoop. All Spark components – Spark Core, Spark SQL, DataFrames, Data sets, Conventional Streaming, Structured Streaming, MLlib, Graphx and Hadoop core components – HDFS, MapReduce and Yarn are explored in greater depth with implementation examples on Spark + Hadoop clusters. It is moving away from MapReduce to Spark. So, advantages of Spark over MapReduce are explained at great depth to reap benefits of in-memory speeds. DataFrames API, Data Sources API and new Data set API are explained for building Big Data analytical applications. Real-time data analytics using Spark Streaming with Apache Kafka and HBase is covered to help building streaming applications. New Structured streaming concept is explained with an IOT (Internet of Things) use case. Machine learning techniques are covered using MLLib, ML Pipelines and SparkR and Graph Analytics are covered with GraphX and GraphFrames components of Spark. Readers will also get an opportunity to get started with web based notebooks such as Jupyter, Apache Zeppelin and data flow tool Apache NiFi to analyze and visualize data.

Chapter 7. Machine Learning with Spark and Hadoop

We have discussed a typical life cycle of a data science project in Chapter 1, Big Data Analytics at a 10,000-Foot View. This chapter, however, is aimed at learning more about machine learning techniques used in data science with Spark and Hadoop.

Data science is all about extracting deep meaning from data and creating data products. This requires both tools and methods such as statistics, machine learning algorithms, and tools for data collection and data cleansing. Once the data is collected and cleansed, it is analyzed using exploratory analytics to find patterns and build models with the aim of extracting deep meaning or creating a data product.

So, let's understand how these patterns and models are created. This chapter is divided into the following subtopics:

  • Introducing machine learning

  • Machine learning on Spark and Hadoop

  • Machine learning algorithms

  • Examples of machine learning algorithms

  • Building machine learning pipelines

  • Machine learning...
