In their own words
Hadoop Distributed File System
Hadoop Distributed File System (HDFS) is the primary distributed storage used by Hadoop applications. Its clusters use a NameNode to manage filesystem metadata and DataNodes to store data. HDFS is designed for fault tolerance on commodity hardware and high-throughput streaming access and batch processing, not low latency. It is tuned for files from gigabytes to terabytes, clusters with hundreds of nodes, and tens of millions of files in one instance. Administration includes shell-like commands, NameNode and DataNode web servers, fsck diagnostics, safemode, and a cluster balancer. Its permissions model shares much with POSIX and can optionally use POSIX ACLs; authentication supports simple operating-system identity or Kerberos. Configured encryption protects data at rest and in transit using encryption zones and the Hadoop Key Management Server. WebHDFS provides a REST API, and listed storage integrations include Amazon S3, Azure Blob Storage, Azure Data Lake Storage, and Tencent COS. HDFS is free to use under Apache License 2.0, with self-hosted cluster deployment.
