presto superset connection

Hi All,

Am trying to use cassandra via Presto on Apache superset.

what is the SQLAlchemy URI that we need to pass.

I have tried giving presto://cassandra:cassandra@localhost:9042/test

for which it is throwing below error message.

"ERROR: {"error": "Connection failed!\n\nThe error message returned was:\n(builtins.ValueError) Protocol must be https when passing a password [SQL: 'SHOW TABLES']"}"

case2:: if giving like presto://// --> throwing below error

ERROR: {"error": "Connection failed!\n\nThe error message returned was:\nHTTPConnectionPool(host='none', port=8080): Max retries exceeded with url: /v1/statement (Caused by NewConnectionError(': Failed to establish a new connection: [Errno -2] Name or service not known',))"}

Please advise me. Thanks
