> 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.
