Apache Hadoop

Apache Hadoop is an open-source framework for distributed storage and processing of large datasets across clusters of computers using simple programming models. It includes HDFS for distributed storage, YARN for resource management, and MapReduce for parallel data processing.

Apache Hadoop publishes 4 APIs on the APIs.io network, including WebHDFS API, YARN Applications API, YARN Cluster API, and 1 more. Tagged areas include Big Data, Data Processing, Distributed Computing, HDFS, and MapReduce.

Apache Hadoop’s developer surface includes documentation, getting-started guide, changelog, and 8 more developer resources.
