jealous commented on issue #24462: [SPARK-26268][CORE] Do not resubmit tasks when executors are lost URL: https://github.com/apache/spark/pull/24462#issuecomment-487837772 Hi @Ngone51 , our shuffle manager is an in-place replacement of the vanilla shuffle manager. It allows the user to write the shuffle file to external storage. The files could be located with the app id, shuffle id, mapper id and reducer id so that we don't need an extra registry for the shuffle files. And yes, we don't rely on an `ExternalShuffleService`.
