Pavel Yaskevich updated CASSANDRA-1427:
---------------------------------------

    Attachment: CASSANDRA-1427-v3.patch

All things from your previous comment are implemented + MoveTest old content is moved to LeaveBootstrapTest
(I think it is still useful) and MoveTest itself is updated.

> Currently our move/loadbalance operations only implement case 2 of the Ruhl algorithm
described at https://issues.apache.org/jira/browse/CASSANDRA-192#action_12713079.
> We should add functionality to optimize moves that take/give ranges to a node's direct
neighbors.
