> I found an inconsistency in [validation logic of Spark submit arguments
> |https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmitArguments.scala#L248-L258]that
> allows *spark.driver.cores* value to be set to 0 but requires
> *spark.driver.memory,* *spark.executor.cores, spark.executor.memory* to be
> positive numbers:
> {quote}Exception in thread "main" org.apache.spark.SparkException: Driver
> memory must be a positive number
> Exception in thread "main" org.apache.spark.SparkException: Executor cores
> must be a positive number
> Exception in thread "main" org.apache.spark.SparkException: Executor memory
> must be a positive number
> {quote}
> I would like to understand if there is a reason for this inconsistency in the
> validation logic or it is a bug?
> Thank you
