I’am trying to connect Cassandra cluster
Steps to replicate the issue -
Settings -> New Data Source -> Select “Cassandra” -> Host
if I set single IP address in Host then it connects but i have a Cassandra cluster of 3 nodes
192.168.0.1,192.168.0.2,192.168.0.3
This gives error as Name or service unknown.

The problem here is you can’t put multiple IP addresses in the data source setup screen. The idea behind the Cassandra cluster is that each node can talk to the others for load balancing. You’re not supposed to talk with all three nodes at once 
For it to work, use one of the IP addresses that the cluster listens on.
