HDFS (Hadoop Distributed File System) is a distributed file system designed to run on commodity hardware. It provides high throughput access to application data and is suitable for applications that have large data sets. HDFS differs from traditional file systems in several ways, including its architecture based on a master-slave model with NameNode and DataNodes; its ability to handle very large files and manage data across multiple nodes; its tolerance to hardware failures through replication and data block placement strategies; and its support for efficient data processing using MapReduce.
