> Key: SPARK-4236
> URL: https://issues.apache.org/jira/browse/SPARK-4236
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.2.0
> Reporter: Aaron Davidson
> Assignee: Aaron Davidson
> Priority: Critical
> Fix For: 1.2.0
>
>
> When external shuffle service is enabled, executors no longer cleanup their
> own shuffle files, as the external server can continue to serve them. The
> external serer must clean these files up once it knows that they will never
> be used again (i.e., when the application terminates or when Spark's
> ContextCleaner requests that they be deleted).
