> migrated
> ---------------------------------------------------------------------------------
>
> Key: SPARK-41469
> URL: https://issues.apache.org/jira/browse/SPARK-41469
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.1.3, 3.2.2, 3.3.1
> Reporter: wuyi
> Priority: Major
>
> Currently, we will always rerun a finished shuffle map task if it once runs
> the lost executor. However, in the case of the executor loss is caused by
> decommission, the shuffle data might be migrated so that task doesn't need to
> rerun.
