I thought of documenting my Kafka learning process so one might find this helpful.
How to start the broker:
$ ./zookeeper-server-start.sh -daemon /home/bershath/apps/kafka/kafka_2.13-3.1.0.redhat-00004/config/zookeeper.properties
#Verify the existence of zookeeper
$ jcmd | grep zookeeper
$ ./kafka-server-start.sh -daemon /home/bershath/apps/kafka/kafka_2.13-3.1.0.redhat-00004/config/server.properties
#Verify Kafka is running
$ jcmd | grep kafka
How to send a few messages and receive them to verify the installation
$ ./kafka-topics.sh --bootstrap-server localhost:9092 --create --replication-factor 1 --partitions 1 --topic test
$ ./kafka-topics.sh --bootstrap-server localhost:9092 --describe --topic test
$ ./kafka-console-producer.sh --bootstrap-server localhost:9092 --topic test
$ ./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning
