>
> WritableName.getClass raises an IOException when it cannot load the class. 
> The message is "WritableName can't load class" without the name of the class. 
>  Although one can get this from getCause, easier to see it just from the 
> message.
> propose change it to:
>       IOException newE = new IOException("WritableName can't load class: " + 
> name);
> I will attach a patch.
