Funny that you ask about this, as I was just writing code which required hacking back to the old API because it needed to use MultipleOutputs.
Short answer to say: as far as I can tell, the only way to get MultipleOutputs (or map-side join via CompositeInputFormat) is to go back to the old and ugly JobConf / MapReduceBase API. Sad, but necessary, unless I'm mistaken. -jake On Mon, Dec 19, 2011 at 7:52 PM, Raphael Cendrillon < cendrillon1...@gmail.com> wrote: > A question, is it possible use multiple outputs with the new Hadoop API? > > It seems that multiple outputs were only full ported in Hadoop 0.21, but I > think Mahout uses 0.20. > > Does that mean I need to stick with the old API (JobConf etc.)? > > Thanks! > > Raphael.
