Hadoop is an open-source framework developed by the Apache Software Foundation for reliable, scalable, distributed computing, designed to process large data sets across clusters of computers using simple programming models. It functions as the foundational layer for big data processing within the Apache ecosystem, enabling high-throughput access and fault-tolerant operations across commodity hardware. The core Hadoop platform consists of four key modules: Hadoop Common, which provides shared libraries and utilities; Hadoop Distributed File System (HDFS™), a distributed file system offering high-throughput access to application data; Hadoop YARN, a framework for cluster resource management and job scheduling; and Hadoop MapReduce, a YARN-based system for parallel processing of large data sets. These components collectively enable scalable, distributed data storage and processing. This technology is intended for data engineers, system administrators, and developers who manage or build applications requiring large-scale data processing, as it equips them with the tools to efficiently store, process, and analyze vast volumes of structured and unstructured data across distributed environments.
