Hadoop: Open-Source Framework for Big Data Storage and Processing

Hadoop is an open-source framework that is used to store, process, and analyze large data sets using a distributed computing model. It was developed by Apache Software Foundation and is written in Java. Hadoop consists of two main components - Hadoop Distributed File System (HDFS) and MapReduce. HDFS is a distributed file system that is used to store large data sets across multiple nodes in a Hadoop cluster. MapReduce is a programming model that is used to process large data sets by dividing them into smaller chunks and processing them in parallel on different nodes in the cluster. Hadoop is widely used in Big Data applications and is used by companies like Facebook, Yahoo, and LinkedIn.
