PySpark and AWS: Master Big Data with PySpark and AWS - Hadoop Ecosystem

This video provides an overview of the Hadoop ecosystem, focusing on its core components: HDFS, YARN, and MapReduce. It explains how MapReduce works and its limitations, which led to the development of Spark as a more efficient alternative. Spark retains the underlying MapReduce structure but simplifies the process, making it faster and more reliable. The video concludes with a brief mention of future topics, including a deeper dive into the Spark ecosystem.
