Apache Spark Course for Beginners



Welcome to the Apache Spark Course for Absolute Beginners

This course is designed to help absolute beginners understand big data processing using Apache Spark. No prior experience with distributed computing or cluster frameworks is required.

Why Learn Apache Spark?

What You Will Learn

  1. Big Data Basics – Understand what big data is and why traditional systems fail to scale.
  2. Apache Spark Architecture – Learn how Spark works internally and how it handles distributed data.
  3. RDDs vs DataFrames – Explore Spark’s core abstractions.
  4. PySpark Basics – Work with Spark using Python.
  5. Spark SQL – Query structured data with SQL on Spark.
  6. DataFrames & Transformations – Clean and analyze large datasets.
  7. Spark Streaming – Handle real-time data streams.
  8. Machine Learning with Spark MLlib – Build and evaluate ML models using large datasets.
  9. Project – Real-world Spark project to consolidate learning.
