Here is what I did:
{noformat}
ccm create 2177 -p OrderPreservingPartitioner
ccm add node2 -i 127.0.0.2 -j 7200 -s -n N
ccm add node1 -i 127.0.0.1 -j 7100 -s -n a
ccm add node3 -i 127.0.0.3 -j 7300 -s -n z
create keyspace bar with placement_strategy=NetworkTopologyStrategy and
strategy_options=[{datacenter1: 2}];
Address Status State Load Owns Token
z
127.0.0.2 Up Normal 50.65 KB 33.33% N
127.0.0.1 Up Normal 50.65 KB 33.33% a
127.0.0.3 Up Normal 50.65 KB 33.33% z
{noformat}
(Note that capital letters sort before lower-case ones.)
getRangeToEndpointMap(bar) is (a,z]:[127.0.0.3, 127.0.0.2], (z,N]:[127.0.0.2,
127.0.0.1], (N,a]:[127.0.0.1, 127.0.0.3]
all nodes are represented twice.
