Apache Hadoop 2 (Hadoop 2.0) is the second iteration of the Hadoop framework for distributed data processing Hadoop 2 adds support for running non-batch applications through the introduction of YARN, a redesigned cluster resource manager that eliminates Hadoop's sole reliance on the Map Reduce programming model. Short for yet another resource negotiator, YARN puts resource management and job scheduling functions in a separate layer beneath the data processing one, enabling Hadoop 2 to run a variety of applications. Overall, the changes made in Hadoop 2 position the framework for wider use in big data analytics and other enterprise applications.
