Hadoop is an open-source framework designed to handle vast amounts of structured and unstructured data by distributing storage and computation across a cluster of commodity hardware. At the core of Hadoop is its master/slave architecture, which enables efficient management of large-scale datasets. The Hadoop Distributed File System (HDFS) is the storage layer of Hadoop, optimized for high-throughput access to large files, fault tolerance, and scalability. HDFS follows a master/slave design, where the master node, known as the NameNode, coordinates the system, and the slave nodes, called DataNodes, handle the actual storage of data __________ __________ ____ ______ _______ ____ ______ ___ _________ _____ _____.
