This three-day introductory course focusses on helping participants gain a thorough understanding of maintaining a Hadoop cluster and its components. Compared to other cluster architectures, Hadoop s designed for massive scalability and has superior fault tolerance. The course also covers how to install, configure and maintain Hadoop on Linux in various computing environments.
