  Hadoop   Apache Hadoop is a free and open source platform for storing and processing huge datasets ranging in size from gigabytes to petabytes. Hadoop allows clustering several computers to analyse big datasets in parallel, rather than requiring a single large computer to store and analyse the data. Hadoop makes it easy to make use of all of a cluster server's storage and processing capability, as well as to run distributed operations on massive volumes of data. Hadoop provides the foundation for the development of other services and applications. By connecting to the NameNode via an API call, applications that collect data in multiple formats can place data into the Hadoop cluster. The NameNode, which is duplicated among DataNodes, keeps track of the file directory structure and placement of "chunks" for each file. It Provide a MapReduce job made up of several map and reduce jobs that runs on the data in HDFS scattered across the DataNodes to run a job to query ...
