Hi Saptarshi, AFAIK, this is an intermediate stage where the old api is supported, while evolving the new api. In 0.21, the old api - MultipleOutputFormat is not deprecated. http://hadoop.apache.org/mapreduce/docs/r0.21.0/api/index.html.In future it might be.

So what you need should be the deciding factor. And ofcourse, a wary user is a smart user! Thanks & Regards, /Rekha.

Going forward, will the latter be deprecated? Which is better to use? I prefer the latter but since it isn't in o.a.h.mapreduce i'm wary it might be discontinued. Regard Saptarshi
