Review comment:
@tgravescs `exec.hostPort` or `exec.host` will be only called when
there's a corresponding `LiveExecutor`. And `LiveExecutor` is added either by
`onExecutorAdded` or `onBlockManagerAdded`, and `onExecutorAdded` set the
`host` and `onBlockManagerAdded` set the `hostPort`. So, `host` and `hostPort`
can't be `null` at the same time.
