dtarima opened a new pull request #33251: URL: https://github.com/apache/spark/pull/33251
### What changes were proposed in this pull request? There was a regression since Spark started storing large remote files on disk (https://issues.apache.org/jira/browse/SPARK-22062). In 2018 a refactoring introduced a hidden reference preventing the auto-deletion of the files (https://github.com/apache/spark/commit/a97001d21757ae214c86371141bd78a376200f66#diff-42a673b8fa5f2b999371dc97a5de7ebd2c2ec19447353d39efb7e8ebc012fe32L1677). Since then all underlying files of DownloadFile instances are kept on disk for the duration of the Spark application which sometimes results in "no space left" errors. ### Why are the changes needed? Long-running Spark applications require freeing resources when they are not needed anymore, and iterative algorithms could use all the disk space quickly too. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Added a test in BlockManagerSuite and tested manually. -- This is an automated message from the Apache Git Service.
