Hadoop Introduction submitted By Anurag Sharma Department of Computer Science and Engineering Indian Institute of Technology Bombay. It enables data to be stored at multiple nodes in the cluster which ensures data security and fault tolerance. data (for example, text, pictures) and determine how to deal with it later. Hadoop naturally stores numerous duplicates of all data, and if one node fails while processing data. Hadoop is supplied by Apache as an open source software framework. • HDFS is designed to ‘just work’, however a working knowledge helps in diagnostics and improvements.
