Is it possible to create cassandra cluster with two data centers?
dc1 - two node docker containers on the same host
dc2 - one node data center
When i tried the same, from dc2 it is failing to seed from dc1 nodes.
I think this is the information you're searching for: https://docs.datastax.com/en/cassandra/3.0/cassandra/initialize/initMultipleDS.html
Basically, you set the DC information in cassandra-rackdc.properties.
