Where can you find the spark-submit script in a Spark installation?

The spark-submit script is located in the "bin" directory of a Spark installation. This script is essential for submitting Spark applications to a cluster, allowing users to easily execute their jobs with specific configurations and options defined at runtime. The "bin" directory contains various executable scripts and programs that enable users to interact with Spark, including other utilities required for the cluster operation.

The "sbin" directory is typically used for scripts that are meant for controlling Spark's cluster management, such as starting and stopping the Spark services. The "conf" directory holds configuration files for Spark, such as the core site configuration and environment variables, but it does not contain executable scripts. Similarly, the "lib" directory is dedicated to the libraries and dependencies required by Spark, rather than any executable scripts. Understanding the purpose of each of these directories helps clarify why the "bin" directory is the correct answer for locating the spark-submit script.
