-------------------------------------
Summary: Add missing config sasl.mechanism.controller.protocol
Key: KAFKA-12374
URL: https://issues.apache.org/jira/browse/KAFKA-12374
Project: Kafka
Issue Type: Bug
Components: config
Affects Versions: 2.8.0
Reporter: Ron Dagostino
Assignee: Ron Dagostino
Fix For: 2.8.0
The config `sasl.mechanism.controller.protocol` from KIP-631 is not
implemented. Furthermore, `KafkaRaftManager` is using inter-broker security
information when it connects to the Raft controller quorum. KafkaRaftClient
should use the first entry in `controller.listener.names` to determine the
listener name; that listener name's mapped value in the
`listener.security.protocol.map` (if such a mapping exists, otherwise the
listener name itself) for the security protocol; and the value of
`sasl.mechanism.controller.protocol` for the SASL mechanism. Finally,
`RaftControllerNodeProvider` needs to use the value of
`sasl.mechanism.controller.protocol` instead of the inter-broker sasl mechanism
(it currently determines the listener name and security protocol correctly)
