I set on a ubuntu node of a cluster a kafka 0.11.0.0 instance. Until some weeks ago everything worked fine, today I'm trying to starting it and I obtain this error after the boot:
[2017-09-11 16:21:13,894] INFO [Kafka Server 0], started (kafka.server.KafkaServer)
[2017-09-11 16:21:18,998] WARN Connection to node 0 could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)
[2017-09-11 16:21:21,991] WARN Connection to node 0 could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)
... and so on...
My server.properties:
############################# Server Basics #############################
The id of the broker. This must be set to a unique integer for each broker.
broker.id=0
Switch to enable topic deletion or not, default value is false
delete.topic.enable=true
############################# Socket Server Settings ##########################$
The address the socket server listens on. It will get the value returned from
java.net.InetAddress.getCanonicalHostName() if not configured.
FORMAT:
listeners = listener_name://host_name:port
EXAMPLE:
listeners = PLAINTEXT://your.host.name:9092
#listeners=PLAINTEXT://9092
Hostname and port the broker will advertise to producers and consumers. If no$
it uses the value for “listeners” if configured. Otherwise, it will use the $
returned from java.net.InetAddress.getCanonicalHostName().
advertised.listeners=PLAINTEXT://hidden_ip:55091
I edited advertised.listeners because there is a proxy to redirect requests to the broker. Anyway until some weeks ago everything worked fine...
My step to start kafka:
1- service zookeeper start
2- ./kafka_2.11-0.11.0.0/bin/kafka-server-start.sh ~/kafka_2.11-0.11.0.0/config/server.properties
Any advises? Thank you
