Cluster Performance Tuning

About this Course

This course teaches you to tune MapR XD and YARN parameters to optimize cluster performance. After setting up your cluster to run batch YARN jobs, the next steps are to run complex real-time queries on data. You will learn how to re-evaluate cluster resources and make modifications to ensure that both types of jobs - realtime and batch - can run effectively and efficiently.
