Hello Katriel, Are you using replication factor 3? So it seems that in us-east it's all fine with each machine having 100% of the data. The problem is in eu-west where you have unbalanced nodes. You should rearrange the tokens in that eu-west DC.
Check e.g. this token calculator to calculate good tokens: http://www.geroba.com/cassandra/cassandra-token-calculator/ Info about rebalancing the cluster: http://www.datastax.com/dev/blog/balancing-your-cassandra-cluster BR, Hannu 2013/11/13 Katriel Traum <katr...@google.com> > Hello list, > > I have a problem with my cluster ownership not being as expected. > > I have 2 DC cluster using NetworkTopologyStrategy on and > EC2MultiRegionSnitch with cassandra 1.1.5.
