Apache Spark Certification Practice Test

Apache Spark indeed supports multiple programming languages, which includes not only its primary languages, Java and Scala, but also other languages such as Python and R. While Clojure is not one of the officially supported languages in the sense that there's no dedicated API provided by Apache Spark specifically for it, developers often leverage Clojure’s interoperability with Java since Clojure runs on the Java Virtual Machine (JVM). This feature enables Clojure developers to interact with Spark libraries by calling Java methods, effectively using Spark with Clojure.

Thus, the assertion that Spark supports Clojure recognizes the flexibility afforded by its JVM compatibility, allowing those who use Clojure to utilize Spark's powerful data processing capabilities, albeit indirectly through inter-language functionality. Therefore, the notion of broad support for multiple languages, including Clojure, captures this nuanced relationship.
