Patricio Echague commented on CASSANDRA-2882:
---------------------------------------------
I tested with Two Datacenters now:
{code}
Address DC Rack Status State Load Owns
Token
147817752135733713663542323384546292869

147817752135733713663542323384546292869
{code}
and I still get the same behavior as shown previously (two nodes with empty
EndpointDetails and the coordinator with the populated entity but null in the
dc field , even though I have two datacenters now).

> describe_ring is great for getting a list of nodes in the cluster, but it
> doesn't provide any information about the network topology which prevents
> it's use in a multi-dc setup. It would be nice if we added another list to
> the TokenRange object containing the DC information.
> Optimally I could have ask any Cassandra node for this information and on the
> client-side prefer local nodes but be able to fail to remote nodes without
> requiring another lookup.
