Is Apache Spark moving to Java?

Apache Spark isn't exactly "moving" to Java, but it does provide a Java API, in addition to its Scala, Python, and R APIs ¹. This means that developers can use Spark from Java, and the project provides Java-specific documentation and examples ². In fact, Spark's Java API is designed to be similar to its Scala API, with some differences to accommodate Java's type system and lack of implicit conversions ². Spark's Java API includes classes like `JavaSparkContext` and `JavaRDD`, which provide the same functionality as their Scala counterparts, but with Java-specific methods and types ². This allows Java developers to use Spark's features, such as RDDs, DataFrames, and machine learning algorithms, from their Java code. That being said, Spark is still primarily developed in Scala, and its core engine is written in Scala ¹. However, the project's goal is to provide a unified engine for large-scale data analytics that can be used from multiple programming languages, including Java ³. So, while Spark isn't "moving" to Java, it does provide strong support for Java developers who want to use its features. If you're interested in using Spark from Java, I'd recommend checking out the project's Java documentation and examples, which provide a great starting point for getting started ². read less
