> The fallback storage removes migrated shuffle data on Spark context shutdown.
> Ideally, it should remove individual shuffles once they get removed from the
> Spark context. Otherwise, all shuffle data ever migrated to the fallback
> storage accumulate on the remote storage until the Spark context shuts down.
> For long running jobs with a lot of decommissioning, this can be orders of
> magnitude more data than what is actively been used / usable / referenced.
