Hadoop and Spark Fundamentals for Big Data

Modern organizations generate massive amounts of data every day, making traditional storage and processing systems obsolete. To work with big data, you need to understand the powerful distributed frameworks designed to handle scalability and speed. This course provides a clear, text-based introduction to the world of big data processing using Hadoop and Spark. You will start with the absolute basics, learning the core terminology, architectural concepts, and the fundamental differences between disk-based and in-memory processing. What you'll learn: Understand the foundational architecture of the Hadoop ecosystem, including HDFS and YARN; Write basic MapReduce concepts to process large datasets; Configure and run Spark applications using Resilient Distributed Datasets (RDDs) and DataFrames; Compare disk-based batch processing with real-time in-memory data processing; Practice writing structured queries using Spark SQL on distributed data; Apply modern data engineering workflows including basic integration with cloud storage. We begin by exploring the foundational concepts of distributed storage and resource management, ensuring you have a solid grasp of how cluster computing works. From there, you will progress to writing data processing workflows, learning how to query and manipulate large datasets using Spark SQL and DataFrames. This course is designed specifically for beginners with no prior experience in big data technologies, though a basic familiarity with programming concepts is helpful. Start reading today to build a strong foundation in modern big data engineering.
