I'm still using the old API for most of my mapreduce jobs - we used to use
Apache Hadoop 0.20.1 and the new API was embarrassingly incomplete and
buggy. I'm aware that a lot of the missing features (MultipleInputs etc)
have since been added in later versions but I've stuck with the old because
I trust it more.

Until the old API is killed off by Hadoop - and I don't mean the
half-hearted deprecation that was reverted in the 0.21 branch - I think we
should continue to fully support it on mrunit too.

Cheers,
Dave
