-----------------------------------
Summary: Spark allows to set spark.driver.cores to 0
Key: SPARK-35013
URL: https://issues.apache.org/jira/browse/SPARK-35013
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 3.1.1, 2.4.7
Reporter: Oleg Lypkan
I found an inconsistency in validation logic of Spark submit arguments 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 any reason for this inconsistency in the
validation logic or it is a bug?
Thank you
