Dongjoon Hyun updated SPARK-31346:
----------------------------------
Affects Version/s: (was: 3.0.1)
> Add new configuration to verify temporary directory cleaned
> -----------------------------------------------------------
>
> Key: SPARK-31346
> URL: https://issues.apache.org/jira/browse/SPARK-31346
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Jackey Lee
> Priority: Major
>
> In InsertIntoHiveTable and InsertIntoHiveDirCommand, we use
> deleteExternalTmpPath to clean temporary directories after Job committed and
> cancel deleteOnExit if succeeded. But sometimes (e.g., when speculative task
> is enabled), temporary directories may be left uncleaned. This is happened if
> there are still some tasks running after we called deleteExternalTmpPath.
> Thus it maybe necessary to keep deleteOnExit, even if temporary directory has
> already deleted, to verify the temporary directories cleaned.
