Hadoop distributed file system or hdfs is a java based distributed file system that allows you to store large data across multiple nodes in a hadoop cluster. Hadoop allows big problems to be decomposed into smaller elements so that analysis can be done quickly and cost effectively. Otherwise it would be best to stick with a traditional database to meet data storage and analytics needs. The blocks are stored on data nodes, and it is the responsibility of the namenode to know what blocks on which data nodes make up the complete file.
