Hadoop is used for research and production by various companies and organizations.
Through the Apache Hadoop Project, an open-source software for reliable, scalable, and distributed computing will be developed.
The Apache Hadoop software library, a framework for distributed processing of large data sets across clusters of computers, was designed to scale up to single servers to thousands of machines that have their own computation and storage.
Instead of relying on hardware to provide high availability, Apache Hadoop’s library was designed to detect and handle failures at the application layer.
This helps it to deliver a highly-available service that’s on top of a group of computers, each of which may be prone to failures. The project includes Hadoop Common, Hadoop Distributed File System, Hadoop Yarn, and Hadoop MapReduce.
