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 .



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?
