Jiang Xingbo resolved SPARK-24340.
----------------------------------
Resolution: Fixed
> Clean up non-shuffle disk block manager files following executor death
> ----------------------------------------------------------------------
>
> Key: SPARK-24340
> URL: https://issues.apache.org/jira/browse/SPARK-24340
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.4.0
> Reporter: Jiang Xingbo
> Priority: Major
>
> Currently we only clean up local folders on application removed, and we don't
> clean up non-shuffle files, such as temp. shuffle blocks, cached
> RDD/broadcast blocks, spill files, etc. and this can cause disk space leaks
> when executors periodically die and are replaced.
> To avoid this source of disk space leak, we can clean up executor disk store
> files except for shuffle index and data files on executor finished.
