Why is Apache spark programmed in Scala?
1) Apache Spark is written in Scala and because of its scalability on JVM – Scala programming is most prominently used programming language, by big data developers for working on Spark projects. Also, the performance achieved using Scala is better than many other traditional data analysis tools like R or Python.
What is Spark and Scala used for?
Usage. Spark is used to increase the Hadoop computational process. Scala can be used for web applications, streaming data, distributed applications and parallel processing. Hence, this is also an important difference between Spark and Scala.
Is Scala necessary for spark?
You will need to use a compatible Scala version (2.10. x).” Java is a must for Spark + many other transitive dependencies (scala compiler is just a library for JVM). PySpark just connects remotely (by socket) to the JVM using Py4J (Python-Java interoperation).
Should I use Scala or Java for spark?
In the world for backward compatibility Java is way ahead of Scala. The reason folks use Scala over Java is because Spark was created in Scala, and when Spark was an incubator project at Apache, as new APIs were exposed, the Scala API’s came first, and then they were ported to Python/Java.
What is Spark implemented in?
Scala
Fewer Lines of Code: Although Spark is written in both Scala and Java, the implementation is in Scala, so the number of lines is relatively lesser in Spark when compared to Hadoop.
What is Scala used for?
Why use Scala? It is designed to grow with the demands of its user, from writing small scripts to building a massive system for data processing. Scala is used in Data processing, distributed computing, and web development. It powers the data engineering infrastructure of many companies.
Why is Scala used?
Why Scala is used in big data?
The main reason for using Scala in these environments is due to its amazing concurrency support, which is the key in parallelizing processing of the large data sets. Scala runs on the JVM, hence Java classes and libraries may be used directly in Scala code and vice versa.
What are the languages supported by Apache Spark?
pySpark (Python)

What is Apache Spark?
Apache Spark. Apache Spark is a lightning-fast cluster computing technology,designed for fast computation.
What is Scala in Apache?
Scala: The powerhouse of Apache Spark. Scala, which is an acronym for Scalable Language, is a multi-paradigm, statically-typed, type-safe programming language focused on Web services. Widely used by data scientists today, its popularity is set to soar in the future because of the boom in the Big Data and data science domains.
