> Components: Spark Core, YARN
> Affects Versions: 1.1.0
> Reporter: Chengxiang Li
>
> With SPARK-3174, one can configure a minimum and maximum number of executors
> for a Spark application on Yarn. However, the application always starts with
> the maximum. It seems more reasonable, at least for Hive on Spark, to start
> from the minimum and scale up as needed up to the maximum.
