Hi there,

I had a 3 nodes ring, added a 4th one,  and moved others to appropriate tokens..doing nodetool ring shows:

127.0.0.1       datacenter1 rack1       Up     Normal  348.82 MB       25.00%  0                                           
127.0.0.2       datacenter1 rack1       Up     Normal  349.81 MB       25.00%  42535295865117307932921825928971026432      
127.0.0.3       datacenter1 rack1       Up     Normal  437.04 MB       25.00%  85070591730234615865843651857942052864      
127.0.0.4       datacenter1 rack1       Up     Normal  261.74 MB       25.00%  127605887595351923798765477786913079296 

Although it shows 25% on all nodes, the data distribution seems totally unbalanced, how did that happen? 
Also if I happen to have a thousand node cluster, and add another 100 nodes, is it ok to start moving all nodes to their respective new tokens simultaneously or one-by-one?
Any response is appreciated.
