> Rename hostPort to host because executorIdToHost stores only the hostname (or
> IP), not the host:port combination. This improves code clarity and prevents
> potential misuse.
> {code:scala}
> // TaskSchedulerImpl.resourceOffers
> executorIdToHost(o.executorId) = o.host
> {code}
> so, when we get host from executorIdToHost, we should us host instead of
> hostPort.
> {code:scala}
> // TaskSchedulerImpl.executorLost
> val hostPort = executorIdToHost(executorId)
> {code}
