            The Apache Hadoop software library is a framework that allows for
            the distributed processing of large data sets across clusters of
            computers using a simple programming model. It is designed to
            scale up from single servers to thousands of machines, each
            offering local computation and storage. Rather than rely on
            hardware to deliver high-avaiability, the library itself is
            designed to detect and handle failures at the application layer,
            so delivering a highly-availabile service on top of a cluster of
            computers, each of which may be prone to failures.
