Introducing YARN

The Yet Another Resource Negotiator (YARN) separates the resource management, scheduling, and processing components. It helps to achieve 100% resource utilization of the cluster resources. YARN manages the CPU and memory of the cluster based on the Hadoop scheduler policy. YARN supports any type of application and is not restricted to just MapReduce. It supports applications written in any type of language, provided binaries can be installed on the Hadoop cluster.
