Architecture of Hadoop
Hadoop is an open-source framework written in java that enables the distributed process of enormous datasets across clusters of computers victimization straightforward programming models. The Hadoop framework application works in open-source network that gives distributed storage and computation across clusters of computers. Hadoop is meant to proportion from a single server to thousands of machines, every providing native computation, and storage. Hadoop design At its core, Hadoop has 2 major layers particularly particularly Processing/Computation layer (MapReduce), and Storage layer (Hadoop Distributed file system). MapReduce MapReduce may be a parallel programming model for writing distributed applications devised at Google for the economical process of enormous amounts of information (multi-terabyte data-sets), on massive clusters (thousands of nodes) of trade goods hardware in an exceedingly reliable, fault-tolerant manner. The MapReduce program runs on Hadoop that is an ope...
