Hi, I am working on Kafka Authorization using Kafka-ACL. I had enabled the aithorization configuring following in server.properties file
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer super.users=User:CN=pxrdc.myhost.com I executed following command to add ACL on topic test ./bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer –authorizer-properties zookeeper.connect=localhost:12181 \ –add –allow-principal User:CN=pxrdc.myhost.com \ --operation All –topic test Now, when I publish messages to Kafkabroker, I am getting following error $ bin/sasl-kafka-console-producer.sh --broker-list localhost:19092 --topic test --producer.config config/client-sasl.properties >message1 [2017-10-05 16:09:52,001] WARN Error while fetching metadata with correlation id 1 : {test=UNKNOWN_TOPIC_OR_PARTITION} (org.apache.kafka.clients.NetworkClient) [2017-10-05 16:09:52,001] WARN Error while fetching metadata with correlation id 3 : {test=UNKNOWN_TOPIC_OR_PARTITION} (org.apache.kafka.clients.NetworkClient) If I open kafka-authorizer.log, I am seeing error for the same User to not have access of Principal "User:CN=pxrdc.myhost.com" Want to understand if any specific configuration also needs to be added to make it work.
