Kafka TOPIC_AUTHORIZATION_FAILED

I'm actually working on setting up simple Kafka authentication using SASL Plain Text and add ACL authorization. But I have an issue when I try to consume data.

Next, you can see my configuration files.

kafka_server_jaas.conf

KafkaServer {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="admin"
  password="admin-secret"
  user_admin="admin-secret"
  user_alice="alice-secret";
};

KafkaClient {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="alice"
  password="alice-secret";
};

Environment variable:

export KAFKA_OPTS="-Djava.security.auth.login.config=/home/user/kafka_2.10-0.10.0.1/kafka_server_jaas.conf"

Commands

Set ACL:

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:alice --operation All --group test-consumer-group --topic test-topic

start Kafka Server :

./bin/kafka-server-start.sh config/server.properties

Start Producer:

bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test-topic --producer.config=config/producer.properties

Start Consumer:

bin/kafka-console-consumer.sh --new-consumer --zookeeper localhost:2181 --topic test-topic --from-beginning --consumer.config=config/consumer.properties  --bootstrap-server=localhost:9092

When I try to start the consumer, I have the issue described above. Also, in the kafka logs, I have this:

[2016-10-22 20:17:14,091] ERROR [KafkaApi-0] Error when handling request {group_id=test-consumer-group} (kafka.server.KafkaApis)

    at kafka.server.KafkaRequestHandler.run(KafkaRequestHandler.scala:60)
    at java.lang.Thread.run(Thread.java:745)

How can I fix this?

Solution

  • Issue fixed by separating jaas client and jaas server.

    kafka_server_jaas.conf

    KafkaServer {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="admin"
  password="admin-secret"
  user_admin="admin-secret"
  user_alice="alice-secret";
};

    kafka_client_jaas.conf

    KafkaClient {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="alice"
  password="alice-secret";
};

    On the same terminal, export jaas server conf file and start kafka broker:

    $ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/user/kafka_2.10-0.10.0.1/kafka_server_jaas.conf"
$ ./bin/kafka-server-start.sh config/server.properties

    On a client terminal, export client jaas conf file and start consumer:

    $ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/user/kafka_2.10-0.10.0.1/kafka_client_jaas.conf"
$ ./bin/kafka-console-consumer.sh --new-consumer --zookeeper localhost:2181 --topic test-topic --from-beginning --consumer.config=config/consumer.properties  --bootstrap-server=localhost:9092

    If you also want to produce, do this on another terminal window:

    $ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/user/kafka_2.10-0.10.0.1/kafka_client_jaas.conf"
$ ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test-topic --producer.config=config/producer.properties
