Apache Hadoop

Apache Hadoop is an open-source framework for distributed storage and processing of large data sets on computer clusters. The project includes the Hadoop Distributed File System (HDFS) for storing data across machines, and a parallel processing system called MapReduce that schedules jobs across the cluster. Hadoop has evolved beyond these two core components, with new additions such as YARN, which is a resource management layer responsible for managing resources in a multi-tenant environment. It can also integrate with other Apache projects like Hive (data warehousing), Pig (dataflow scripting), HBase (NoSQL database), Spark (in-memory processing engine) and many others to extend its capabilities. This extensibility allows users to build out their own big data solutions within the Hadoop ecosystem tailored specifically to their needs without having to rely on proprietary software or hardware vendors' offerings.
