Hi,=20

Just wondering if there is any particular reason that 'mapred.join= ' package never found its way into 'mapreduce'. Being in the ol= d space makes its use rather inconvenient when most of its former neighbors= now happily live in the new package.

Is this package recommended for prod at all, or maybe, there is an alt= ernative?

Thanks,
