Output file name

In a Hadoop job, how do I set the prefix of the output files to something different than "part-" ?

I mean, what should I do if I want my output files to be named "piece-00000" instead of "part-00000"?

Cheers,
Rodrigo

You need to implement your own OutputFormat.
See MultipleOutputFormat class for examples.
