Scala for Cloudera Training in Denmark

Cloudera University’s one-day Scala training course will teach you the key language concepts and programming techniques you need so that you can concentrate on the subjects covered in Cloudera’s Spark-related training courses without also having to learn a complex programming language at the same time.

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.

There are no prerequisites for this course.

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.

Through instructor-led discussion or OnDemand videos, as well as hands-on exercises, participants will learn:

• What Scala is and how it differs from languages such as Java or Python 
• Why Scala is a good choice for Spark programming 
• How to use key language features such as data types, collections, and flow control
