About this Course

This course is for cluster administrators who will be managing and running YARN jobs on the cluster. It covers installing YARN services, and the flow of YARN job execution. You will learn about YARN logging options, and how to change how resources are allocated to YARN. Finally, you will learn about the job schedulers available to YARN, how to select the one that is most appropriate for your cluster, and how to control job placement and resource allocation.
