> If the namenode is in safe mode for some reason then FileSystemNodeLabelStore will prevent
the RM from starting since it unconditionally tries to create the root directory for the label
store.  If the root directory already exists and no labels are changing then we shouldn't
prevent the RM from starting even if the namenode is in safe mode.
