Event logs in Spark are log files that record detailed information about the various stages and tasks performed during the execution of a Spark application. These logs include information such as the start of Spark jobs, task execution, data reading and writing, etc., which can help users understand the progress of Spark application execution, optimize performance, and debug issues.
