> Allow dynamic allocation without an external shuffle service
> ------------------------------------------------------------
>
> Key: SPARK-27963
> URL: https://issues.apache.org/jira/browse/SPARK-27963
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: Marcelo Masiero Vanzin
> Assignee: Marcelo Masiero Vanzin
> Priority: Major
> Labels: release-notes
> Fix For: 3.0.0
>
>
> It would be useful for users to be able to enable dynamic allocation without
> the need to provision an external shuffle service. One immediate use case is
> the ability to use dynamic allocation on Kubernetes, which doesn't yet have
> that service.
> This has been suggested before (e.g.
> https://github.com/apache/spark/pull/24083, which was attached to the
> k8s-specific SPARK-24432), and can actually be done without affecting the
> internals of the Spark scheduler (aside from the dynamic allocation code).
