not even number of keys per CFs in fully balanced cluster with random partitioner

Hi, There is a 12 node cluster , still stuck on 1.0.8. All nodes in the cluster ring are balanced. Using random partitioner. All CFs use compression. Data size on nodes varies from 40G to 75G. This variance is not due to the bigger nodes having more uncompacted sstables than others. Most bigges
