Instructions on Starting Kafka

1. Create zookeeper-logs directory (mkdir zookeeper-logs)

2. Modify config/zookeeper.properties dataDir to point to zookeeper-logs (full path)

3. Run Zookeeper
   Unix: /bin/zookeeper-server-start.sh kafka/config/zookeeper.properties Windows: /bin/windows/zookeeper-server-start.bat config/zookeeper.properties

4. Create 3 directories, one for each Kafka broker logs: mkdir kafka-logs-0 mkdir kafka-logs-1 mkdir kafka-logs-2

5. Create 2 copies of config/server.properties and name them config/server-1.properties and config/server-2.properties. Rename the original config/server.properties to config/server-0.properties.

6. Change each configuration file's log.dirs to point to the corresponding kafka-logs-X directory.

7. In server-1.properties uncomment the #listeners=PLAINTEXT://:9092 and change the port to 9093

8. In server-2.properties uncomment the #listeners=PLAINTEXT://:9092 and change the port to 9094

9. Run 3 Kafka brokers pointing to the corresponding properties files: Unix: bin/kafka-server-start.sh /config/server-0.properties & bin/kafka-server-start.sh /config/server-1.properties & bin/kafka-server-start.sh /config/server-2.properties & Windows: bin/windows/kafka-server-start.bat /config/server-0.properties & bin/windows/kafka-server-start.bat /config/server-1.properties & bin/windows/kafka-server-start.bat /config/server-2.properties &

10. Create valid-transactions Kafka topic: bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 3 --partitions 3 --topic valid-transactions

11. Create suspicious-transactions Kafka topic: bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 3 --partitions 2 --topic suspicious-transactions
