cloud-fan commented on issue #25795: [WIP][SPARK-29037][Core] Spark gives duplicate result when an application was killed URL: https://github.com/apache/spark/pull/25795#issuecomment-533393396 > Before per insert, we should check the path whose name is started with .spark-staging and find the longest path with sp_ prefix. The problem here is that, how do you detect `insert overwrite table ta select ...`? `.spark-staging-${UUID}` always exists if there is an ongoing write.
