----------------------------------------
Summary: Security without JAAS file
Key: KAFKA-13055
URL: https://issues.apache.org/jira/browse/KAFKA-13055
Project: Kafka
Issue Type: Bug
Components: security
Reporter: Alexey Kashavkin
I'm setting up kafka security with multiple listeners. Listener for broker
works as plaintext and I don't want to use authentication for them. My cluster
has configuration:
{code:bash}
listeners=BROKERS://:9091,CLIENTS://:9092,CLIENTS-NOSSL://:9093inter.broker.listener.name=BROKERS
sasl.enabled.mechanisms=SCRAM-SHA-256listener.security.protocol.map=BROKERS:PLAINTEXT,CLIENTS:SASL_SSL,CLIENTS-NOSSL:SASL_PLAINTEXT
{code}
For clients, I want use SCRAM and only for them (not for brokers). But when I
start broker, I see following message in log:
{code:bash}
ERROR [KafkaServer id=0] Fatal error during KafkaServer startup. Prepare to
shutdown (kafka.server.KafkaServer)
java.lang.IllegalArgumentException: Could not find a 'KafkaServer' or
'clients.KafkaServer' entry in the JAAS configuration. System property
'java.security.auth.login.config' is not set
{code}
Why is this file so need, if I don't use authentication for brokers and SCRAM
mechanism stores credentials in zookeeper? I didn't find any information about
it in [docs|http://kafka.apache.org/documentation/#security].
