> Key: SPARK-19349
> URL: https://issues.apache.org/jira/browse/SPARK-19349
> Project: Spark
> Issue Type: Improvement
> Components: DStreams
> Affects Versions: 2.0.2, 2.1.0
> Reporter: Genmao Yu
>
> Currently, we can only ensure registered resource satisfy the
> "spark.scheduler.minRegisteredResourcesRatio". But if
> "spark.scheduler.minRegisteredResourcesRatio" is set too small, receivers may
> still be scheduled to few nodes. In fact, we can give once more chance to
> wait for sufficient resource to schedule receiver evenly.
