Detailed explanation-1: -Apache Hadoop YARN (Yet Another Resource Negotiator) is a cluster management technology. It is a resource-management platform responsible for managing computing resources in clusters and using them for scheduling of users’ applications. It allows Hadoop to do more than just MapReduce data processing jobs.
Detailed explanation-2: -One of Apache Hadoop’s core components, YARN is responsible for allocating system resources to the various applications running in a Hadoop cluster and scheduling tasks to be executed on different cluster nodes.
Detailed explanation-3: -APACHE AMBARI It includes software for provisioning, managing and monitoring Apache Hadoop clusters.
Detailed explanation-4: -The Scheduler is responsible for allocating resources to the various running applications subject to familiar constraints of capacities, queues etc. The Scheduler is pure scheduler in the sense that it performs no monitoring or tracking of status for the application.
Detailed explanation-5: -Resource Manager: It is the core component of Yarn and is considered as the Master, responsible for providing generic and flexible frameworks to administer the computing resources in a Hadoop Cluster.
