> URL: https://issues.apache.org/jira/browse/SPARK-3795
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 1.1.0
> Reporter: Patrick Wendell
> Assignee: Andrew Or
> Fix For: 1.2.0

>
> To support dynamic scaling of a Spark application, Spark's scheduler will
> need to have hooks around explicitly decommissioning executors. We'll also
> need basic heuristics governing when to start/stop executors based on load.
> An initial goal is to keep this very simple.
