How to balance this cluster out ?

[Oleg Dulin]

I have a cluster that looks like this:

Datacenter: us-east
==========
Replicas: 2
Address         Rack        Status State   Load            Owns         
      Token
                                                                       
      113427455640312821154458202477256070484
*.*.*.1   1b          Up     Normal  141.88 GB       66.67%             
56713727820156410577229101238628035242
*.*.*.2  1a          Up     Normal  113.2 GB        66.67%              210
*.*.*.3   1d          Up     Normal  102.37 GB       66.67%             
113427455640312821154458202477256070484


Obviously, the first node in 1b has 40% more data than the others. If I 
wanted to rebalance this cluster, how would I go about that ? Would 
shifting the tokens accomplish what I need and which tokens ?
