    Description

      Similar to #3821. but affecting normal columns.

      Set up a 2-node cluster with rf=2.
      1. Create a counter column family and increment a 100 keys in loop 5000 times.
      2. Then make a rolling restart to cluster.
      3. Again increment another 5000 times.
      4. Make a rolling restart to cluster.
      5. Again increment another 5000 times.
      6. Make a rolling restart to cluster.

      After step 6 we were able to reproduce bug with bad counter values.
      Expected values were 15 000. Values returned from cluster are higher then 15000 + some random number.
      Rolling restarts are done with nodetool drain. Always waiting until second node discover its down then kill java process.
