Hadoop

An open source software platform for processing very large datasets in a distributed environment with respect to storage and computational power, mainly built on low-cost commodity hardware. It is designed for easy scale up from a few to thousands of servers. It will help to process locally stored data in an overall parallel processing setup. It comprises different modules–Hadoop Distributed File System (HDFS), Hadoop MapReduce, and Hadoop YARN (Yet Another Resource Negotiator).
