Thanks, that clarifies why HH did not work, So have to use .7. Is there .6.7 ? I am using .6.6 now. I did see the log entry in Node 4, adding a Hint for Node 2 and when Node 2 came up noticed a log entry in Node 4 that 1 row Handed Off - so I thought it was working. About RR - a read in Node 1 or

My findings - would be nice if somebody can please verify. Critical for our eval to verify HintedHandOff, ReadRepair and AntiEntropy works as we think it does Node 1, 2, 3, 4 RF=3 All nodes up - Node 2 is responsible for key 1005 Write CL=ONE, Insert key 1005, value=123 in Node 1 Node 2, 3, 4 get
