cloud-fan edited a comment 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-533176585 > We can check the existence of output path like the FileOutputFormat did. How does it work for `dynamicPartitionOverwrite=true`? The output path is staging dir which is unique. Can we detect 2 jobs that are writing to the same table with `dynamicPartitionOverwrite=true`?
