Subject Configuring the keyspace correctly - NTS
Date Wed, 14 Sep 2011 21:43:49 GMT
Okay, in a previous post, it was stated that I could use a
NetworkTopologyStrategy in a singel data centre by setting up my keyspace

create keyspace KeyspaceDEV

    with placement_strategy =

    and strategy_options=[{datacenter1:3}];

Whereby my understanding is that:



   - 1 Datacentre
   - 3 nodes in that datacentre

My infrastructure team were recommended to instead of use "datacenter1" to
use the second value in the IP address:


However, when trying to access the keyspace the following error was return:

"May not be enough replicas present to handle consistency level"
When I rebuilt the keyspace using the "datacenter1" semantic, it worked

My guess is that there is some correlation between the "130" value and
either the rpc_address or listen_address. Am I correct in thinking this?

I don't have access to the se configurations so I'm just going out on a whim
here trying to figure out why using the "130" form the IP address would
cause the error.
