--------------------------------------
Not really enough info here. How does it happen?
> Sparksql temporary file conflict
> --------------------------------
>
> Key: SPARK-42714
> URL: https://issues.apache.org/jira/browse/SPARK-42714
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.3.2
> Reporter: hao
> Priority: Major
>
> When sparksql inserts overwrite, the name of the temporary file in the middle
> is not unique. This will cause that when multiple applications write
> different partition data to the same partition table, it will be possible to
> delete each other's temporary files between applications, resulting in task
> failure
