'''Apache Hadoop'''は[[フリーソフトウェア|フリー]]の[[Java]][[ソフトウェアフレームワーク]]であり、大規模データの分散アプリケーションをサポートする。<ref>"Hadoop is a framework for running applications on large clusters of commodity hardware. The Hadoop framework transparently provides applications both reliability and data motion. Hadoop implements a computational paradigm named map/reduce, where the application is divided into many small fragments of work, each of which may be executed or reexecuted on any node in the cluster. In addition, it provides a distributed file system that stores data on the compute nodes, providing very high aggregate bandwidth across the cluster. Both map/reduce and the distributed file system are designed so that node failures are automatically handled by the framework."
