> Currently the APIs for safe-mode are part of DistributedFileSystem, which is
> supposed to be a private interface. However, dependent software often wants
> to wait until the NN is out of safemode. Though it could poll trying to
> create a file and catching SafeModeException, we should consider making some
> of these APIs public.
