I'm using 1.0.0 beta, suppose it was wrong decision to use beta version.
So do you recommend using 0.20.203.X and stick to Hadoop definitive
guide approaches?
Thanks for your reply

Oh and btw, do not fear the @deprecated 'Old' API. We have
undeprecated it in the recent stable releases, and will continue to
support it for a long time. I'd recommend using the older API, as that
is more feature complete and test covered in the version you use.

What version/release/distro of Hadoop are you using? Apache releases
got the new (unstable) API MultipleOutputs only in 0.21+, and was only
very recently backported to branch-1.
That said, the next release in 1.x (1.1.0, out soon) will carry the
new API MultipleOutputs, but presently no release in 0.20.xxx/1.x has
it.
I'd still recommend sticking to stable API if you are using a
0.20.x/1.x stable Apache release.

Hello,
I'm trying to develop an application, where Reducer has to produce multiple
outputs.
In detail I need the Reducer to produce two types of files. Each file will
have different output.
I found in Hadoop, The Definitive Guide, that new API uses only
MultipleOutputs, but working with MultipleOutputs requires JobConf instace,
that is @deprecated (I'm using org.apache.hadoop.mapreduce.Job instance to
handle job configuration).
So I'm wondering how to get MultipleOutputs working.
Can you please provide me some short example or explanation.
Thanks for your reply.
