-------------------------------------------
Ok cluster testing complete and all looks good!
I just noticed a SerializationTest started failing though, Can you take a look

> The use of IP addresses as node identifiers in the partition of a given
> counter is fragile. Changes of the node's IP addresses can result in data
> loss. This patch proposes to use UUIDs instead.
> NOTE: this breaks the on-disk file format (for counters)
