May be relevant?

What RF is this cluster? Given beta and cluster size and data size
this small, I would probably just dump and reload instead of trying to
make shuffle work.

going away in Cassandra 2.0.

Eric Evans gave a talk at the summit during which he attempted to
communicate that people probably shouldn't use shuffle. Given that he
is the one who wrote the shuffle patch, this seems like a meaningful
data point... :)
