Add File Header Using FileOutputFormat

Hi all!
I'm using hadoop to make huge weka learning files. As you know,  weka file
(ARFF) has some speicial file headers. Is there a way for me to add it at
the beginning of the file using FileOutputFormat? If so, how can I do that?

Thanks!

Regards
Song Liu

write the header in setup method if you are using new hadoop API.
