turboFei edited a comment on issue #26086: [SPARK-29302] Make the file name of a task for dynamic partition overwrite and specified abs path be unique URL: https://github.com/apache/spark/pull/26086#issuecomment-540982545 Oh, It seems that this issue is related with https://github.com/apache/spark/pull/24142. I just read the comments of that, it seems that there are some risk that cause duplicate result. @ajithme @vanzin @LantaoJin How about using this method to name a task file for dynamic partition overwrite only? Because for this cases, it will keep a filesToMove set, which would not cause duplicate result. P.S: I doubt whether it would cause duplicate result for non dynamic partition overwrite case. Should outputCommitCoordinator decide which task can commit?
