Matt Cheah commented on SPARK-1860:
-----------------------------------
This might be a silly question, but are we guaranteed that the application
folder will always be labeled by appid? I looked at ExecutorRunner and it
certainly generates the folder by application ID and executor ID, but code
comments in ExecutorRunner indicate it is only used by the standalone cluster
mode. Hence I didn't tie any logic to the actual naming of the folders.
> 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.
