How to setup superset to authenticate against druid with kerberos enables

New Contributor

we have a HDP 2.6.2 cluster with kerberos enabled. Kerberos authentication is enabled. No problems accessing the consoles, but the dashboards fail with an authentication error.

HTTP Error 403: org.apache.hadoop.security.authentication.client.AuthenticationException: GSSException: Failure unspecified at GSS-API level (Mechanism level: Invalid argument (400) - Cannot find key of appropriate type to decrypt AP REP - RC4 with HMAC) Druid Error: None Query is: { "postAggregations": [], "queryType": "topN", "aggregations": [ { "type": "count", "name": "count" } ], "metric": "count", "dataSource": "EN-42181-MAX-DEV-EPG-PORTAL_CLICKSTREAM_EVENT", "intervals": "2017-08-21T16:47:08+00:00/2018-08-21T16:47:08+00:00", "dimension": "Browser", "granularity": "all", "threshold": 5000 }
