What is the Spark architecture?

Spark Architecture Overview Apache Spark has a well-defined layered architecture where all the spark components and layers are loosely coupled. This architecture is further integrated with various extensions and libraries. Apache Spark Architecture is based on two main abstractions: Resilient Distributed Dataset (RDD)

What are the components of Spark architecture?

Below are the high-level components of the architecture of the Apache Spark application:

• The Spark driver. The driver is the process “in the driver seat” of your Spark Application.
• The Spark executors.
• The cluster manager.
• Cluster mode.
• Client mode.
• Local mode.

Is Spark a framework?

Spark is an open source framework focused on interactive query, machine learning, and real-time workloads. Spark on Hadoop leverages YARN to share a common cluster and dataset as other Hadoop engines, ensuring consistent levels of service, and response.

What is Spark and Scala?

Spark is an open-source distributed general-purpose cluster-computing framework. Scala is a general-purpose programming language providing support for functional programming and a strong static type system. Thus, this is the fundamental difference between Spark and Scala.

Is spark similar to SQL?

Spark SQL is a Spark module for structured data processing. It provides a programming abstraction called DataFrames and can also act as a distributed SQL query engine. It enables unmodified Hadoop Hive queries to run up to 100x faster on existing deployments and data.

Is spark a programming language?

SPARK is a formally defined computer programming language based on the Ada programming language, intended for the development of high integrity software used in systems where predictable and highly reliable operation is essential. SPARK 2014 is a complete re-design of the language and supporting verification tools.
