[jira] [Created] (KAFKA-14111) Dynamic config update fails for "password" configs in KRaft
David Arthur created KAFKA-14111:
------------------------------------
Summary: Dynamic config update fails for "password" configs in KRaft
Key: KAFKA-14111
URL: https://issues.apache.org/jira/browse/KAFKA-14111
Project: Kafka
Issue Type: Bug
Reporter: David Arthur
Two related bugs found when working on updating DynamicBrokerReconfigurationTest for KRaft.
Firstly, if we issue an AlterConfig (or IncrementalAlterConfig) for a broker config that is defined as a "password", it will succeed on the controller, but throw an error when the broker handles it.
For example, on a vanilla cluster running "config/kraft/server.properties"
{code}
/bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter --broker 1 --add-config listener.name.external.ssl.key.password=foo
{code}
results in
{code}
[2022-07-26 16:24:05,049] ERROR Dynamic password config listener.name.external.ssl.key.password could not be decoded, ignoring. (kafka.server.DynamicBrokerConfig)
