Course description

Tackle Hadoop tools and services like NiFi, YARN, and Flume as well as the Spark shell, an alternative to MapReduce. Discover why Hadoop has such a large and growing following among sys admins and data scientists. Learning how Hadoop has something for just about everybody to gain and maintain competitive advantage.

Prerequisites

You should have some programming background and some familiarity with a Unix-based operating system. No specific experience with Java programming language or Hadoop is required. As with any such course, the more experience you bring to the course, the more you’ll get out of it. This course moves quickly through a broad range of topics, but it does not require any prior experience with Hadoop. The course does assume that you are well familiarized with how to use the version of Windows that you are running. For example, the course might say simply “Open PuTTY” without explaining how to do that. You should also be able to navigate the folder hierarchy using Windows Explorer.
