why is scala better than java for spark?

It can work with JVM and is therefore portable. It can comfortably support Java APIs. It is fast and robust in the context of Spark as it is native to Spark. Yes, it may seem more complex to the Scala novice, but once you fully understand the concepts behind it, Scala code will seem much more simplistic than Java code.

Some of the more complex features of the language (tuples, functions, macros, to name a few) ultimately make it easier for the developer to write better code and increase performance when programming in Scala. Scala is a type-safe JVM language that incorporates both object-oriented and functional programming in an extremely concise, logical and extraordinarily powerful language. As a result, there are certainly code distinctions and paradigm shifts that can make initially learning to program in Scala a bit more difficult, but the result is a much cleaner, well-organised language that is ultimately easier to use and increases productivity. Scala is enough to give you a preview of Scala's power and capabilities and whet your appetite for learning the language.

ZDNet cites Scala as one of the most popular programming languages that can get you a job interview. Scala's popularity and usage is growing rapidly, as evidenced by the increasing number of job openings for Scala developers. You will master the essential skills of the open source Apache Spark framework and the Scala programming language. Many organisations favour the speed and simplicity of Spark, which supports many application programming interfaces (APIs) available from languages such as Java, R, Python and Scala.

This Spark certification training course helps you master both the essential skills of the Apache Spark open source framework and the Scala programming language.
