Cassandra connection from ADB

[Dinu2]

Hi , Could anyone please help to know the steps for connecting Cassandra from Azure Databricks? I have followed the steps in https://learn.microsoft.com/en-us/azure/databricks/_static/notebooks/azure/cassandra-azure.html But I am getting below error.

IOException: Failed to open native connection to Cassandra at {<<hostname>>:<<portno>>} :: Could not reach any contact point, make sure you've provided valid addresses (showing first 1 nodes, use getAllErrors() for more): Node(endPoint=/<<hostname>>:<<portno>>, hostId=null, hashCode=5079251a): [com.datastax.oss.driver.api.core.auth.AuthenticationException: Authentication error on node /<<hostname>>:<<portno>>: Node /<<hostname>>:<<portno>> requires authentication (com.datastax.bdp.cassandra.auth.DseAuthenticator), but no authenticator configured]
