Vitalii Bashun "First Spark application in one hour"

The document provides an introduction to creating a first Spark application in one hour. It begins with an overview of Hadoop and why Spark became an industry standard due to its ability to keep intermediate data in memory for faster processing. The key concepts covered are Spark Session, which acts as the entry point for Spark programming, and Resilient Distributed Datasets (RDDs), DataFrames, and Datasets, which are the main abstractions Spark uses for distributed data. The document concludes by stating it will demonstrate creating a hands-on first Spark application using the Spark Shell.
