>                 Key: SPARK-26340
>                 URL: https://issues.apache.org/jira/browse/SPARK-26340
>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 2.2.2, 2.3.2
>            Reporter: Nicolas Fraison
>            Priority: Minor
>
> No check is performed to ensure spark.task.cpus is lower then spark.executor.cores. Which can lead to jobs not able to assign tasks without any understandable issues
> The check is only performed in the case of dynamic allocation usage in ExecutorAllocationManager
> Adding the check in TaskSchedulerImpl ensure that an issue is thrown to the driver
