I use Ubuntu server 16.04 to try using Kafka, for the command to start producer and consumer console i use
Producer console :
bin/kafka-console-producer.sh --broker-list localhost:9092 --topic hello-topic
consumer console :
bin/kafka-console-consumer.sh --zookeeper localhost:2181 --from-beginning --topic hello-topic
but command above only subsribe to one topic, how can i subsribe to multiple topic?
Thanks.
