Nick Bailey commented on CASSANDRA-1427:
----------------------------------------
bq. 1). What should we do with the ranges left on the node if we are moving to
the completely new range (no intersection with old range), should we stream
them to the ring?
We should just follow the same strategy decom uses. Any ranges that this node
owned before the move should be streamed to anyone who will become a new
replica for that data.
bq. 2). Should we do 1). always (on any move)?
Yes.

> Currently our move/loadbalance operations only implement case 2 of the Ruhl
