I strongly disagree. I think it's unnecessary, and I think it breaks the model too much. Google has many thousands of map reduce applications, and they haven't broken the model yet. I don't really care about output formats, but I think we're just asking for trouble if we allow the type of the reduce output to be different from the type of the map output. -- Andrew McNabb http://www.mcnabbs.org/andrew/ PGP Fingerprint: 8A17 B57C 6879 1863 DE55 8012 AB4D 6098 8826 6868
