Hadoop Yarn

Hadoop YARN (Yet Another Resource Negotiator) is a component of Apache Hadoop that allows multiple data processing engines such as Apache Pig, Apache Hive, and Apache Spark to run on a single Hadoop cluster. It is a resource management layer that allows users to manage and allocate resources in a Hadoop cluster to run various applications. YARN provides a central platform for managing, scheduling, and monitoring distributed computing jobs on a Hadoop cluster. It also enables running non-MapReduce distributed applications in Hadoop, such as real-time streaming and graph processing. YARN splits the resource management and job scheduling functions of the Hadoop Distributed File System (HDFS) and MapReduce, making Hadoop more versatile and efficient.
