Hadoop Platform

Hadoop Platform is a framework which holds open source software utilities that expedite using several computers which are interconnected by network in order to provide solution to problems involving a huge chunk of data and computation. Distributed storage and processing of Big Data is handled using a software framework known as MapReduce programming model which was initially designed for computer cluster developed from commodity hardware. The platform is made up two parts, the first which is Hadoop Distributed File System (HDFS) is the storage part which handles the modal by which data are stored, and the second part MapReduce programming model which handles how data are being distributed. It accomplishes this by splitting files into large blocks and distributes them transversely within nodes in a cluster. In order to process this data, it transfers the appropriate package code into the nodes. The platform is written in several programming language like java programming language and some native code which was written in C language and its command line utilities which was written as a shell scripts. The java code implementation for the map and reduce is accessible to user who intends adopting its use in any section of his program that requires “map” and “reduce” implementation.
