koertkuipers commented on issue #22598: [SPARK-25501][SS] Add kafka delegation token support. URL: https://github.com/apache/spark/pull/22598#issuecomment-486803142 this is exciting to me. i tested it on a kafka 2.2.0 cluster that uses gssapi/kerberos for authentication, by enabling token support in kafka. to be specific in server.properties i changed: ``` - sasl.enabled.mechanisms=GSSAPI + sasl.enabled.mechanisms=GSSAPI,SCRAM-SHA-256,SCRAM-SHA-512 + delegation.token.master.key=somesecret ``` note that i kept `sasl.mechanism.inter.broker.protocol=GSSAPI` i could see my spark structured streaming job obtain kafka token successfully. after that i ran into some issues in driver that seemed kafka specific. i added comments here: https://issues.apache.org/jira/browse/KAFKA-7631
