Detailed explanation-1: -HDFS (Hadoop Distributed File System) is the primary storage system used by Hadoop applications. This open source framework works by rapidly transferring data between nodes. It’s often used by companies who need to handle and store big data.
Detailed explanation-2: -What is HDFS? HDFS is a distributed file system that handles large data sets running on commodity hardware. It is used to scale a single Apache Hadoop cluster to hundreds (and even thousands) of nodes. HDFS is one of the major components of Apache Hadoop, the others being MapReduce and YARN.
Detailed explanation-3: -HDFS employs a NameNode and DataNode architecture to implement a distributed file system that provides high-performance access to data across highly scalable Hadoop clusters. Hadoop itself is an open source distributed processing framework that manages data processing and storage for big data applications.
Detailed explanation-4: -HDFS is a filesystem designed for storing very large files with streaming data access patterns, running on clusters of commodity hardware. Very large files: “Very large” in this context means files that are hundreds of megabytes, gigabytes, or terabytes in size.
