> Currently, BootstrapStandby will only download the latest FSImage if it has
> formatted the local image directory. This can be an issue when there are out
> of date FSImages on a Standby NameNode, as the non-interactive mode will not
> format the image directory, and BootstrapStandby will return an error code.
> The changes here simply allow BootstrapStandby to download the latest FSImage
> to the image directory, without needing to format first.
