> When a channel fails currently we just log the failure. Since we don't wait
> on open requests from every place, checking requests doesn't get called
> always, and we've seen issues with jobs staying stuck, for example during the
> input stage when request for split to read from worker to master fails. When
> we know that channel failed, we should try to resend the requests from that
> channel.
