BoYang resolved SPARK-34601.
----------------------------
Resolution: Won't Fix
> Do not delete shuffle file on executor lost event when using remote shuffle
> service
> -----------------------------------------------------------------------------------
>
> Key: SPARK-34601
> URL: https://issues.apache.org/jira/browse/SPARK-34601
> Project: Spark
> Issue Type: New Feature
> Components: Shuffle
> Affects Versions: 3.2.0
> Reporter: BoYang
> Priority: Major
> Labels: shuffle
>
> There are multiple work going on with disaggregated/remote shuffle service
> (e.g. [LinkedIn
> shuffle|https://engineering.linkedin.com/blog/2020/introducing-magnet],
> [Facebook shuffle
> service|https://databricks.com/session/cosco-an-efficient-facebook-scale-shuffle-service],
> [Uber shuffle service|https://github.com/uber/RemoteShuffleService]). Such
> remote shuffle service is not Spark External Shuffle Service. It could be
> third party shuffle solution and user uses it by setting
> spark.shuffle.manager. In those systems, shuffle data will be stored on
> different server other than executor. Spark should not mark shuffle data lost
> when the executor is lost. We could add a Spark configuration to control this
> behavior. By default, Spark still mark shuffle file lost. For
> disaggregated/remote shuffle service, people could set the configure to not
> mark shuffle file lost.
