Request Info
Description
Scala is a programming language that is a superset of Java, blending the object-oriented and the functional programming paradigms. The language is complex and could take a semester or more to master. This class focuses only on the elements that are necessary to be able to program in Cloudera’s training courses.
PUE, Cloudera Strategic Partner, is authorized by this multinational to provide official training in Cloudera technologies.
Furthermore, PUE is accredited and recognized to offer consulting and mentoring services on the implementation of Cloudera solutions for business environment with the consequent added value in the practical and business knowledge delivered in their official courses.
Audience and prerequisites
Basic knowledge of programming concepts such as objects, conditional statements, and looping is required. This course is best suited to students with Java programming experience. Those with experience in another language may prefer the Just Enough Python course. Basic knowledge of Linux is assumed.
Please note that this course does not teach big data concepts, nor does it cover how to use Cloudera software. Instead, it is meant as a precursor for one of our developer-focused training courses that provide those skills.
