---------------------------------
Summary: can not connect to the unsecure port after config
SASL/PLAIN
Key: KAFKA-5558
URL: https://issues.apache.org/jira/browse/KAFKA-5558
Project: Kafka
Issue Type: New Feature
Components: clients
Affects Versions: 0.10.1.1
Reporter: zhu fangbo
Dear All,
I followed modifying sasl mechanism in a running cluster to set a cluster with
one broker using SASL/PLAIN to authorize client. here are configurations：
server config
server.properties：
listeners=PLAINTEXT://:9093,SASL_PLAINTEXT://:9094
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN
authorizer.class.name = kafka.security.auth.SimpleAclAuthorizer
super.users=User:admin
kafka_server_jaas.conf：
KafkaServer {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="admin"
password="admin"
user_admin="admin"
user_alice="alice";
};
My producer configured with security.protocol=SASL_PLAINTEXT and correct
jass.conf can work well when I connect to the secure port(9094)，but when I use
the default security.protocol and connect to unsecure port(9093), the producer
can not fetch metadata：
DEBUG 17:18:10 kafka-producer-network-thread | producer-1 [NetworkClient]
Sending metadata request {topics=[test]} to node -1
WARN 17:18:10 kafka-producer-network-thread | producer-1 [NetworkClient] Error
while fetching metadata with correlation id 0 :
{test=UNKNOWN_TOPIC_OR_PARTITION}
DEBUG 17:18:10 kafka-producer-network-thread | producer-1 [NetworkClient]
Sending metadata request {topics=[test]} to node 1
WARN 17:18:10 kafka-producer-network-thread | producer-1 [NetworkClient] Error
while fetching metadata with correlation id 2 :
{test=UNKNOWN_TOPIC_OR_PARTITION}
Why the unsecure port can not be connected after config sasl authorization?
