> Currently NameNode allows format command while it running. In this case the
> command is executed partially (Lock file is deleted) and an exception thrown.
> Because of this Name Node should be formatted after restart. This sort of
> cases can happen accidentally. To prevent such cases Name Node should not
> execute the format command partially while it is running. It can stright away
> throw exception/log saying, Name Node is running.
