CompTIA Data+ DA0-002 (V2) Practice Question

A data-analytics team is building a new pipeline that will run on a 100-node Apache Spark cluster. The team wants to (1) write code in the same language that Spark itself is implemented in, (2) gain immediate access to Spark's native DataFrame and Dataset APIs when a new Spark version is released, and (3) avoid the extra Py4J (or similar) serialization layer that adds cross-language overhead. According to the CompTIA Data+ list of common programming languages, which language should the team choose?

  • Scala

  • Java

  • Python

  • R
