Matt Cheah commented on SPARK-1860:
-----------------------------------
Apologies for any naivety - this will be the first issue I tackle as a Spark
contributor.
Mingyu and I had a short chat and we thought it would be reasonable for the
Executor to simply clean up its own state when it shuts down. Is there anything
preventing Executor.stop() from cleaning up the app directory it was using?
> Standalone Worker cleanup should not clean up running executors
> ---------------------------------------------------------------
>
> Key: SPARK-1860
> URL: https://issues.apache.org/jira/browse/SPARK-1860
> Project: Spark
> Issue Type: Bug
> Components: Deploy
> Affects Versions: 1.0.0
> Reporter: Aaron Davidson
> Priority: Blocker
>
> The default values of the standalone worker cleanup code cleanup all
> application data every 7 days. This includes jars that were added to any
> executors that happen to be running for longer than 7 days, hitting streaming
> jobs especially hard.
> Executor's log/data folders should not be cleaned up if they're still
> running. Until then, this behavior should not be enabled by default.
