About this Course

Gain the knowledge and skills required to plan, install, maintain, and manage a secure MapR cluster, then manage YARN jobs. Using lecture and labs, you will learn how to design and install a cluster, and perform pre- and post-installation testing. You will configure users and groups and work with key features of a MapR cluster including volumes, snapshots, and mirrors - including how to use remote mirrors for disaster recovery. Also covered are monitoring and maintaining disks and nodes, and troubleshooting basic cluster problems. Finally, you will install YARN services and practice configuring logging and job schedulers.
