> When a fetch failure happens, if the socket has already "connected" it is
> only counted against the first map task. But most of the time it is because
> of an issue with the Node itself, not the individual map task, and as such
> all failures when trying to initiate the connection should count against all
> of the tasks.
> This caused a particularly unfortunate job to take an hour an a half longer
> then it needed to.
