I found the issue by increasing the log level to DEBUG. Basically follow the steps below. I don't use SSL but you will integrate it without any issue.
Following are my configuration files:
server.properties
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer
allow.everyone.if.no.acl.found=true
auto.create.topics.enable=false
broker.id=0
listeners=SASL_PLAINTEXT://localhost:9092
advertised.listeners=SASL_PLAINTEXT://localhost:9092
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
advertised.host.name=localhost
num.partitions=1
num.recovery.threads.per.data.dir=1
log.flush.interval.messages=30000000
log.flush.interval.ms=1800000
log.retention.minutes=30
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
delete.topic.enable=true
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=6000
super.users=User:admin
zookeeper.properties
dataDir=/tmp/zookeeper
clientPort=2181
maxClientCnxns=0
authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider
requireClientAuthScheme=sasl
jaasLoginRenew=3600000
producer.properties
security.protocol=SASL_PLAINTEXT
sasl.mechanism=PLAIN
bootstrap.servers=localhost:9092
compression.type=none
consumer.properties
security.protocol=SASL_PLAINTEXT
sasl.mechanism=PLAIN
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=6000
group.id=test-consumer-group
Now are the most important files for making your server starting without any issue:
zookeeper_jaas.conf
Server {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="admin"
password="admin-secret"
user_admin="admin-secret";
};
kafka_server_jaas.conf
KafkaServer {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="admin"
password="admin-secret"
user_admin="admin-secret";
};
Client {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="admin"
password="admin-secret";
};
After doing all these configuration, on a first terminal window:
Terminal 1 (start Zookeeper server)
From kafka root directory
$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/usename/Documents/kafka_2.11-0.10.1.0/config/zookeeper_jaas.conf"
$ bin/zookeeper-server-start.sh config/zookeeper.properties
Terminal 2 (start Kafka server)
From kafka root directory
$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/usename/Documents/kafka_2.11-0.10.1.0/config/kafka_server_jaas.conf"
$ bin/kafka-server-start.sh config/server.properties
[BEGIN UPDATE]
kafka_client_jaas.conf
KafkaClient {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="admin"
password="admin-secret";
};
Terminal 3 (start Kafka consumer)
On a client terminal, export client jaas conf file and start consumer:
$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/username/Documents/kafka_2.11-0.10.1.0/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
Terminal 4 (start Kafka producer)
If you also want to produce, do this on another terminal window:
$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/username/Documents/kafka_2.11-0.10.1.0/kafka_client_jaas.conf"
$ ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test-topic --producer.config=config/producer.properties
[END UPDATE]
