This helps to allocate resources to particular applications and manage other kinds of resource monitoring tasks. In YARN, an application submission client submits an application to the YARN resource manager. YARN &#8216;schedules\u2019 applications in order to prioritize tasks and maintain big data analytics systems. This is just one part of a greater architecture for aggregating and sorting data, conducting specific queries to retrieve data, and otherwise using Hadoop and related tools to manipulate big data for business intelligence and much more. Businesses use these kinds of platforms to look at supply chains, document product and service operations, keep track of customer information, and for many other kinds of powerful data-driven and automated business processes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What Does Hadoop YARN Mean?
