>
> 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.
