Issue with Kafka input with Logstash

Hello,

try this :

input {
     kafka {
            bootstrap_servers => "host1:port,host2:port"
            topics => ["topicname"]
        }
}

Port will be the kafka port (9092) if you didn't change it.

The zk_connect parameter in consumer configs is deprecated as far as I know.

Hope this helps,
regards,
Jonas
