SAMPLE QUESTION:

Question:

Which of the following describes the Spark driver?

A. The Spark driver is responsible for performing all execution in all execution modes – it is the entire Spark application. B. The Spark driver is fault tolerant – if it fails, it will recover the entire Spark application. C. The Spark driver is the coarsest level of the Spark execution hierarchy – it is synonymous with the Spark application. D. The Spark driver is the program space in which the Spark application’s main method runs, coordinating the Spark entire application. E. The Spark driver is horizontally scaled to increase overall processing throughput of a Spark application.

Correct Answer:

D. The Spark driver is the program space in which the Spark application’s main method runs, coordinating the Spark entire application.

Explanation:

The Spark driver refers to the program space in which the main method of a Spark application runs. It is responsible for coordinating the execution of the entire Spark application. The driver program defines the SparkContext, which serves as the entry point for Spark functionality. It handles the division of the application into tasks, scheduling them on the cluster, and managing the overall execution. The driver communicates with the cluster manager to allocate resources and coordinate the distribution of tasks to worker nodes. It also maintains control and monitoring of the application. Horizontal scaling, fault tolerance, and execution modes are not directly related to the Spark driver.
