Getting reference to input format used by a job

[Nathan Marz]

Hello,

I have an input format which finds all files reachable from a root  
directory, and I want to delete those files found and those files only  
after the job completes. This is tricky because files are being  
constantly added. Is there a way to get a reference to the input  
format used so I can determine which files it chose? Otherwise, is  
there a way for the input format to communicate back to the "main"  
function this information?

Thanks,

Nathan Marz
