I have a problem in a mapreduce job, I want the output file to have the format file-day-26 instead of part-r-00000.

I have tried to accomplish this with the method addNamedOutput(MultipleOutputs), but could only change the part part.

In the old API I see that it is possible to do this with the method generateFileNameForKeyValue(MultipleTextOutputFormat), but I can't use the old API, so I'm wondering if there is something like this in the new API of Hadoop.

Can someone help me?

Thanks.
