Question about MultiFileInputFormat and conf.get( "map.input.file"), and the stability of the result

[Jason Venner]

We have a lot of jobs that check the map.input.file in the configure 
method, and cause the mapper to act differently based on the file name.
We haven't started using the MultiFileInputFormat, but are wondering if 
anyone has a plan for our the map.input.file will appear in the config 
method, and or if this this becomes something you have to check in the 
mapper, rather than the configure method.

Thanks again
