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.
