Unable to Create Druid Data base connection in superset UI

Hi Team ,

I want to create druid sql lab in superset Ui ,but when i created database connection for druid , iam getting following error.

ERROR: {“error”: "Connection failed!\n\nThe error message returned was:\n(pydruid.db.exceptions.ProgrammingError) Unauthorized request. (None): None [SQL: ‘SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES’] (Background on this error at: http://sqlalche.me/e/f405)"}%22%7D)

here im using kerberized cluster ,hdp 3.0.1 ,druid version is 0.12.1,superset version is 0.23 .

Regards,

kryt.

If it’s unauthorized, probably you need to configure Superset to talk Kerberos to Druid.

I have already superset key tab is there. I checked superset and hive it’s working fine,but druid I’m unable to connect. We can enable calcite for druid sqlalchemy in superset? Any property we need to add for Kerberized cluster?

Regards
