Introduction to Hadoop for Developers

Hadoop Essentials

The Introduction to Hadoop for Developers training course teaches the fundamentals of setting up a Hadoop cluster, as well as the “soup” of related technologies like Hive, Pig and Oozie.

You will learn how to access the Hadoop file system, and write MapReduce jobs using Java, Pig, and Hive Oozie, working with your own installation of a Hadoop 2, single node cluster, in hands-on workshops. We will discuss examples of real world Map Reduce jobs, and how Hadoop has solved real world data-intensive processing problems. Then, we will explore the different modes in which Hadoop can be run to support massive amounts of data, as well as your MapReduce jobs during development.

Best of all, you will walk away with a fully configured virtual machine, that can run under VirtualBox or VMWare, with Hadoop and all related technologies installed, configured, and ready to run. The virtual machine will include the necessary development environment (using Eclipse), so you are immediately productive in growing your Hadoop knowledge by using a live environment, without the hassle of having to set one up from scratch.

Prerequisites: Basic Java knowledge (experience with Eclipse is a plus); we recommend courses in our core Java catalog.
