--------------------------------------------------------------------
[~rustyrazorblade] I implemented some dtests and below is the sample output:
{code:java}
Stats for all nodes:
Live: 4
Joining: 0
Moving: 0
Leaving: 0
Unreachable: 0
Data Centers:
dc1 #Nodes: 2 #Down: 0
dc2 #Nodes: 2 #Down: 0
Keyspaces:
system_schema -> Replication class: LocalStrategy {}
system -> Replication class: LocalStrategy {}
system_traces -> Replication class: SimpleStrategy {replication_factor=2}
system_distributed -> Replication class: SimpleStrategy
{replication_factor=3}
system_auth -> Replication class: SimpleStrategy {replication_factor=1}
ks1 -> Replication class: NetworkTopologyStrategy {dc2=5, dc1=3}
ks2 -> Replication class: NetworkTopologyStrategy {dc2=5, dc1=3}
Cluster Information:
Name: test
Snitch: org.apache.cassandra.locator.PropertyFileSnitch
DynamicEndPointSnitch: enabled
Partitioner: org.apache.cassandra.dht.Murmur3Partitioner
Schema versions:
f5abf9f8-8cc6-350f-a128-ab97ea43871d: [127.0.0.4, 127.0.0.3, 127.0.0.2,
127.0.0.1]{code}
I am using assertions to validate the output. Let me know if it looks okay. I
will upload the dtests patch to cassandra-dtests soon.
