> URL: https://issues.apache.org/jira/browse/SPARK-22085
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: liuxian
> Priority: Minor
>
> When the application has no core left，we should not request more executors

> At this time, if not reach `spark.dynamicAllocation.maxExecutors`,
> `spark.dynamicAllocation.maxExecutors`setting is invalid in fact, so we
> should give a warning log.
