I think I'm the biggest single contributor to Mahout over time (? was
at one point), and so by extension Cloudera is. And this new project
is all open source. Surely that's maximally "walking the walk" in
these regards?

Mahout has served well for a long time as measured in Hadoop-years --
like 4+ years. It's still in usable life. I don't think the current
state of the code means it's feasible to truly evolve it towards
things like Hadoop 2, Spark, real-time. That is to say, there are
legitimate reasons to start forward from a new project with different

CDH5 still supports Mahout for sure. Oryx will work on any Hadoop (2)
distro. I hope there is no openness foul here.
