Apache Spark Certification Practice Test

The command used to submit a Spark job in standalone mode is "spark-submit." This command is essential as it allows users to launch a Spark application on a Spark cluster in standalone mode, which is one of the deployment modes offered by Apache Spark.

When you use "spark-submit," you can specify various parameters such as the application JAR file, the main class, any configuration properties, and resources needed (like memory and executors). This flexibility makes "spark-submit" the go-to command for deploying Spark applications effectively.

Other options listed, such as "start-spark," "submit-job," and "run-spark," do not correspond to recognized commands within the Spark framework for submitting jobs. "start-spark" might imply starting the Spark service rather than submitting a job, while "submit-job" and "run-spark" are not standard commands associated with the Spark ecosystem. Thus, "spark-submit" stands out as the correct and recognized command for this purpose.
