Getting Started with Apache Hadoop
MapReduce refers to a framework that runs on a computational cluster to mine large datasets. The name derives from the application of map() and reduce() functions repurposed from functional programming languages. The main advantage of a MapReduce framework is that it allows the application programmers to focus on building business logic without conerning themselves with infrastructure, scalability, network traffic, or multiprocessing issues.
Apache Hadoop is an open source Java framework for implementing reliable and scalable computational networks. It comprises the tools and utilities for data serialization, file system access, and interprocess communication pertaining to MapReduce implementations. So... how do you get started?
