Target Version/s:
During periods of high network (or GC) load, it is not uncommon that IOExceptions crop up around connection failures when fetching shuffle files. Unfortunately, when such a failure occurs, it is interpreted as an inability to fetch the files, which causes us to mark the executor as lost and recompute all of its shuffle outputs.
We should allow retrying at the network level in the event of an IOException in order to avoid this circumstance.
