Open Source Apache Hadoop 2.0 Advances Big Data

Among the key additions in Hadoop 2.0 is a technology called YARN, which Murthy explained is the operating system to run applications such as MapReduce and Storm. “YARN provides resource management in a generic manner,” he said.

Murthy explained that in Hadoop 1.x MapReduce was both the system and the framework. Because it was so deeply intertwined, Hadoop could only do MapReduce there. With YARN, Hadoop evolves beyond just batch process to a model in which data can be processed in real time with Storm and interactive queries can be executed via Hive.
