This do not works. I joined ring with node without bootstrap and result 
is like this:

216.17.99.40    datacenter1 rack1       Up     Normal  1.17 GB         
99.64%  83030609119105147711596238577753588267
64.6.104.18     datacenter1 rack1       Up     Normal  43.15 KB        
0.36%   83648735508289295779178617154261005054

Well, this was expected. But running repair on both nodes didnt do anything:

Data are not moved to new node. Maybe tokens are not too random. I 
deleted new node and retried:

64.6.104.18     datacenter1 rack1       Up     Normal  45.52 KB

and still nothing, while running repair on both nodes.

Can you try this too? i cant get scenario: make 1 node - add data, add 
second node without bootstrap then repair on both work.
