Charles Allen commented on SPARK-1865:
--------------------------------------
This is compounded by the fact that some of the shutdown processes will stop()
during the normal course of the main thread, then will fail to wait for
completion if stop() is ALSO called via the shutdown hook.
> Improve behavior of cleanup of disk state
> -----------------------------------------

> Key: SPARK-1865
> URL: https://issues.apache.org/jira/browse/SPARK-1865
> Project: Spark
> Issue Type: Improvement
> Components: Deploy, Spark Core
> Reporter: Aaron Davidson
>
> Right now the behavior of disk cleanup is centered around the exit hook of
> the executor, which attempts to cleanup shuffle files and disk manager
> blocks, but may fail. We should make this behavior more predictable, perhaps
> by letting the Standalone Worker cleanup the disk state, and adding a flag to
> disable having the executor cleanup its own state.
