-----------------------------------
hi [~astralidea], if I understand correctly, configuring `spark.scheduler.minRegisteredResourcesRatio` may help.

> Key: SPARK-18039
> URL: https://issues.apache.org/jira/browse/SPARK-18039
> Project: Spark
> Issue Type: Bug
> Components: Scheduler
> Affects Versions: 2.0.1
> Reporter: astralidea
> Priority: Minor
>
> receiver scheduling balance is important for me
> for instance
> if I have 2 executor, each executor has 1 receiver, calc time is 0.1s per batch.
> but if I have 2 executor, one executor has 2 receiver and another is 0 receiver ,calc time is increase 3s per batch.
> In my cluster executor init is slow I need about 30s to wait.
> but dummy job only run 4s to wait, I add conf spark.scheduler.maxRegisteredResourcesWaitingTime it does not work.
