YARN, short for “Yet Another Resource Negotiator,” is a key component of the Hadoop architecture. It serves as the resource management layer responsible for allocating resources to various applications running on the cluster. One of its primary functions is to enable efficient utilization of cluster resources, which leads to improved scalability, fault tolerance, and overall system performance. By managing the resources of a Hadoop cluster, YARN allows multiple applications to run concurrently without interfering with each other, ensuring that all resources are used optimally.


MapReduce is a fundamental processing engine that lies at the heart of Hadoop. Its working principle is based on parallel processing, which means that it divides complex data processing tasks into smaller and more manageable chunks. These smaller tasks are then distributed across a cluster of servers for execution in parallel, enabling faster and more efficient data processing. Once completed, the results are consolidated into meaningful insights that can be used to derive useful conclusions and insights. This approach has been widely adopted across a range of industries and has proven to be a powerful tool for big data analytics.
