> Hi,
> We are trying to to add a new Data Center as per the following link.
> http://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_add_dc_to_cluster_t.html
> The problem is that when I run the following command in the original cluster:
> ALTER KEYSPACE carrierdata WITH replication = {'class':
> 'NetworkTopologyStrategy', 'DC1':3,'DC2':3};
> We will get the following error:
> 2016-05-17 19:38:32.920 ERROR 28583 ---
