Way of determining the source of data

[Ranjan Bagchi]

Hi,

I've a bunch of [for example] apache logfiles that I'm searching through.  I 
can process them with:

logs = load 's3://bucket/directory/*' USING LogLoader as (remoteAddr, 
remoteLogname, user, time :chararray, method, uri :chararray, proto, status, 
bytes, referer, userAgent);

Is there any way of getting the name of the file from which logs was pulled 
added to the relation?

Thanks,

Ranjan
