David C Navas created SPARK-27727:
-------------------------------------
Summary: 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
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.
