Here is the latest configuration of the cluster: spark.executor.cores = "15" spark.executor.instances = "10" spark.executor.memory = "10g" These settings are set on a SparkContext when the Spark application is submitted to the cluster. 回答1: You first need to

Why does it not show NumberFormatException and show the result even though result should not be printed instead ? Side Question Whenever I add an alphabet in
