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.
