"Hadoop is an open-source framework for distributed storage and processing of large datasets. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. The main components of a Hadoop application are: 1) HDFS (Hadoop Distributed File System) - a distributed file system that provides high-throughput access to application data. 2) MapReduce - a programming model for processing large datasets in parallel across the nodes in the cluster. 3) YARN (Yet Another Resource Negotiator) - manages the resources of the Hadoop clusters, scheduling jobs and managing MapReduce tasks."n
