Introduction to Big Data with Spark and Hadoop

In this module, you'll gain a fundamental understanding of the Apache Hadoop architecture, ecosystem, practices, and commonly used applications, including Distributed File System (HDFS), MapReduce, Hive, and HBase. You’ll also gain practical skills in hands-on labs when you query the data added using Hive, launch a single-node Hadoop cluster using Docker, and run MapReduce jobs.

In this module, you’ll turn your attention to the popular Apache Spark platform, where you will explore the attributes and benefits of Apache Spark and distributed computing. You'll gain key insights about functional programming and Lambda functions. You’ll also explore Resilient Distributed Datasets (RDDs), parallel programming, resilience in Apache Spark, and relate RDDs and parallel programming with Apache Spark. Then, you’ll dive into additional Apache Spark components and learn how Apache Spark scales with Big Data. Working with Big Data signals the need for working with queries, including structured queries using SQL. You’ll also learn about the functions, parts, and benefits of Spark SQL and DataFrame queries, and discover how DataFrames work with Spark SQL.

In this module, you’ll learn about Resilient Distributed Datasets (RDDs), their uses in Apache Spark, and RDD transformations and actions. You'll compare the use of datasets with Spark's latest data abstraction, DataFrames. You'll learn to identify and apply basic DataFrame operations. You’ll explore Apache Spark SQL optimization and learn how Spark SQL and memory optimization benefit from using Catalyst and Tungsten. Finally, you’ll fortify your skills with guided hands-on lab to create a table view and apply data aggregation techniques.

In this module, you’ll explore how Spark processes the requests that your application submits and learn how you can track work using the Spark Application UI. Because Spark application work happens on the cluster, you need to be able to identify Apache Cluster Managers, their components, and benefits. You’ll also know how to connect with each cluster manager and how and when you might want to set up a local, standalone Spark instance. Next, you’ll learn about Apache Spark application submission, including the use of Spark’s unified interface, “spark-submit,” and learn about options and dependencies. You’ll also describe and apply options for submitting applications, identify external application dependency management techniques, and list Spark Shell benefits. You’ll also look at recommended practices for Spark's static and dynamic configuration options and perform hands-on labs to use Apache Spark on IBM Cloud and run Spark on Kubernetes.

Platforms and applications require monitoring and tuning to manage issues that inevitably happen. In this module, you'll learn about connecting the Apache Spark user interface web server and using the same UI web server to manage application processes. You’ll also identify common Apache Spark application issues and learn about debugging issues using the application UI and locating related log files. Further, you’ll discover and gain real-world knowledge about how Spark manages memory and processor resources using the hands-on lab.

In this module, you’ll perform a practice lab where you’ll explore two critical aspects of data processing using Spark: working with Resilient Distributed Datasets (RDDs) and constructing DataFrames from JSON data. You will also apply various transformations and actions on both RDDs and DataFrames to gain insights and manipulate the data effectively. Further, you’ll apply your knowledge in a final project where you will create a DataFrame by loading data from a CSV file and applying transformations and actions using Spark SQL. Finally, you’ll be assessed based on your learning from the course.
