Hi 

I am using latest JDBC driver 2.7.3 https://www.databricks.com/spark/jdbc-drivers-archive

And my JDBC url comes from JDBC endpoint of Interactive Cluster.

jdbc:databricks://adb-{workspace_id}.azuredatabricks.net:443/default;transportMode=http;ssl=1;httpPath=sql/protocolv1/o/{workspace_id}/{cluster_id};AuthMech=11;Auth_Flow=2;TokenCachePassPhrase=U2MToken;EnableTokenCache=0
