Use Linux and Hadoop for Distributed Computing

People rely on search engines every day to find specific content from the massive amount of data on the Internet. But have you ever wondered how these searches are executed? One method is Apache Hadoop, which is a software framework that can process massive data in a distributed manner. An Application of Hadoop is to index Internet Web pages in parallel. Hadoop i
