Apache Spark Certification Practice Test

Question: 1 / 400

Where will you find the start-master script in a Spark installation?

bin

lib

sbin

The start-master script is located in the sbin directory of a Spark installation. This directory is specifically designated for scripts that are used to start and stop Spark services like the master and worker nodes. The architecture of Spark separates the scripts according to their functionality: while the bin directory contains the primary command-line executables and utilities for users, sbin is reserved for scripts that manage the cluster services.

The lib directory, on the other hand, contains the libraries required by Spark, while the conf directory is meant for configuration files. Neither of these directories is intended for executable or service management scripts. Therefore, finding the start-master script in the sbin directory aligns perfectly with its purpose in managing Spark's cluster operations.
