Peter Velas created CASSANDRA-4436:
--------------------------------------

             Summary: Counters in columns don't preserve correct values after cluster restart
                 Key: CASSANDRA-4436
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4436
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.0.10
            Reporter: Peter Velas


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.
