turboFei 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-532621176 > Then when dynamicPartitionOverwrite=false , if I detect there is sub dir under $table_output/_temporary exists, it should fast fail. With my knowledge. In this PR, When enableDynamicOverwrite is false. Case: tbl_a(c1 int, c2 int) partitioned by (c2) For the sql: `insert overwrite table tbl_a select ...` I can not detect it's destination partition. So I think if I detect there is sub dir under $table_output/_temporary exists, it should fast fail.
