mapper & Exceptions

[Stefan Groschupf <sg...@media-style.com>]

Hi Doug,

a very small improvement suggestion.
Actually the method map in the mapper Interface can throw a IOException.
I would found it better in case it just throw a general Exception  
since a map task can fail for other reasons as well, e.g. a in the  
map search server scenario you suggested.
Makes this sense?
