> Migrate to fallback storage only
> --------------------------------

> Key: SPARK-52506
> URL: https://issues.apache.org/jira/browse/SPARK-52506
> Project: Spark
> Issue Type: Sub-task
> Components: Kubernetes
> Affects Versions: 4.1.0
> Reporter: Enrico Minack
> Priority: Major
> Labels: pull-request-available
>
> Using the storage decommissioning feature with fallback storage on Kubernetes
> allows to migrate shuffle data from executors onto an external cloud storage.
> Currently, this fallback storage can only be used in conjunction with
> migrating shuffle data to other executors. However, those executors are also
> subject of eventual decommissioning, so shuffle data are potentially migrated
> multiple times.
> The user should have the option to migrate shuffle data at most once, and
> that is to the fallback storage only.
