Show cases consuming messages from Apache Kafka.
First you need to run Zookeeper and Kafka(If you haven't yet). Change to bin directory of Kafka and run zookeeper:
./zookeeper-server-start.sh ../config/zookeeper.properties
then you need to run Kafka:
./kafka-server-start.sh ../config/server.properties
Now you are able to run consumer application which consumes messages from event topic.
