Review Comment:
> The running subquery tries to fetch shuffle(that's already cleaned up
after main query's execution completed), causing a Fetch failure and stopping
the SparkContext.
When the main query completes, we actually only clean up the shuffle files
on the executor but we don't clean up `shuffleStatuses` on the driver
(`shuffleStatuses` is only cleaned up by `ContextCleaner` when the shuffle can
not be referenced in terms of GC). So, theoretically, the subquery shouldn't
hit this exception as the shuffle is still referenced by itself. cc @karuppayya
