YARN (Yet Another Resource Negotiator)

YARN, or Yet Another Resource Negotiator, is a technology that helps manage computing resources in large data processing frameworks, like Apache Hadoop. Imagine a busy office where tasks need different tools and spaces to complete. YARN acts like the office manager, efficiently allocating resources, such as memory and processing power, to various tasks. This way, it ensures that all jobs run smoothly and make the best use of available resources, enabling organizations to process big data effectively and quickly.
