-------------------------------------
How about this approach:
https://github.com/apache/spark/pull/16819
> Spark to be smarter about what the upper bound is and to restrict number of
> executor when dynamic allocation is enabled

> Key: SPARK-18769
> URL: https://issues.apache.org/jira/browse/SPARK-18769
> Project: Spark
> Issue Type: New Feature
> Reporter: Neerja Khattar
>
> Currently when dynamic allocation is enabled max.executor is infinite and
> spark creates so many executor and even exceed the yarn nodemanager memory
> limit and vcores.
> It should have a check to not exceed more that yarn resource limit.
