Duration: 4 Days
Overview
In this course, you will work through the entire process of designing and building solutions, including ingesting data, determining the appropriate file format for storage, processing the stored data, and presenting the results to the end-user in an easy-to-digest format. Go beyond MapReduce to use additional elements of the enterprise data hub and develop converged applications that are highly relevant to the business.
