Okay, in a previous post, it was stated that I could use a
NetworkTopologyStrategy in a singel data centre by setting up my keyspace
with:
create keyspace KeyspaceDEV
with placement_strategy =
'org.apache.cassandra.locator.NetworkTopologyStrategy'
and strategy_options=[{datacenter1:3}];
Whereby my understanding is that:
[{datacenter1:3}]
represents:
- 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:
x.130.x.x
[{130:3}]
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
fine.
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.
