YARN : NextGen Hadoop Data Processing Framework

In this BigData world, massive data storage and faster processing is a big challenge.  Hadoop is the solution to this challenge. Hadoop is an open-source software framework for storing and processing big data in a distributed fashion on large clusters (thousands of machines) of commodity (low cost) hardware. Hadoop has two core components, HDFS and MapReduce. HDFS (Hadoop Distributed File System) store massive data into commodity machines in a distributed manner. MapReduce is a distributed data processing framework to work with this massive data.
