Why study this course

This four-day administrator course provides the technical background you need to manage and scale a Cloudera cluster in a development or production environment. This is the core administrator learning path curriculum.

Take your knowledge to the next level with Cloudera’s Administrator Training and Certification. This four-day administrator training course provides participants with a comprehensive understanding of all the steps necessary to operate and maintain a Hadoop cluster using Cloudera Manager. From installation and configuration through load balancing and tuning, this training course is the best preparation for the real-world challenges faced by Cloudera administrators.

Administrators who earn CCA Administrator Certification by sitting an exam subsequent to this course, have demonstrated technical knowledge in the ability to configure, deploy, maintain, and secure an Apache Hadoop cluster.
