Hadoop is an open-source software framework for storing and processing data on commodity hardware clusters. It has a lot of storage for any kind of data, a lot of processing power. Along with that, it can handle almost unlimited concurrent processes or jobs.
Hadoop, created by Doug Cutting and Michael J. Cafarella, uses the MapReduce programming style to store and retrieve data from its nodes more quickly. The Apache Software Foundation manages the framework, which is released under the Apache License 2.0.
