David C Navas updated SPARK-27727:
----------------------------------
Attachment: AsyncDefer.pdf
> Asynchronous ElementStore cleanup should have only one pending cleanup per
> class
> --------------------------------------------------------------------------------
>
> Key: SPARK-27727
> URL: https://issues.apache.org/jira/browse/SPARK-27727
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 2.3.3
> Reporter: David C Navas
> Priority: Major
> Attachments: AsyncDefer.pdf
>
>
> If ElementTrackingStore cleanup work takes too long to run, the asynchronous
> requests to run the cleanup can backup in the executor. Although eventually
> these requests will do nothing (or very little), they are a potential source
> of semi-permanent memory use/leaks.
