> “ Stage Level Scheduling Overview ” in running-on-yarn and running-on-kubernetes
> The description of dynamic partitioning is inconsistent with the code implementation verification.
> In running-on-yarn
> '
> * When dynamic allocation is disabled: It allows users to specify different task resource requirements at the stage level and will use the same executors requested at startup.
> '
> But the implementation is：
> Class：ResourceProfileManager
> Fuc：isSupported
> private[spark] def isSupported(rp: ResourceProfile): Boolean = {
> assert(master != null)
> if (rp.isInstanceOf[TaskResourceProfile] && !dynamicEnabled) {
> if ((notRunningUnitTests || testExceptionThrown) &&
> !(isStandaloneOrLocalCluster || isYarn || isK8s)) {
> throw new SparkException("TaskResourceProfiles are only supported for Standalone, " +
> "Yarn and Kubernetes cluster for now when dynamic allocation is disabled.")
> }
> }
>
> The judgment of this code is that it does not support TaskResourceProfile in Yarn and k8s when dynamic partitioning is closed.
>
> The description in the document does not match, so the document needs to be modified.
