-----------------------------------
Relevant history work: SPARK-17637 and SPARK-43086
> Support bin pack task scheduling on executors
> ----------------------------------------------
>
> Key: SPARK-43086
> URL: https://issues.apache.org/jira/browse/SPARK-43086
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.3.2
> Reporter: Zhongwei Zhu
> Priority: Minor
>
> Dynamic allocation only remove or decommission an idle executor. The default
> task scheduling use round robin to do task assignment on executors.
> For example, we have 4 tasks to run, 4 executors(each has 4 cpu cores).
> Default task scheduling will assign 1 task per executors. With bin pack, one
> executor could assign 4 tasks, then dynamic allocation could remove other 3
> executors to reduce resource waste.
