Question: I need to supply the Kafka port number and Zookeeper port number for firewall exceptions. Where can I find the port number details for both Kafka and Zookeeper ?
Answer : To find the Kafka port number – locate the Kafka server.properties file. Typically the server.properties file will have the information required. The file is normally found on this location . By default the port number is 9092.
$(confluent_home)/etc/kafka/server.properties
To find the Zookeeper port number – locate the Zookeeper properties file. Normally found on $(confluent_home)/etc/kafka/zookeeper.properties. Once you’ve opened the file , look for ClientPort=2181
For Zookeeper –
2181 = Client connections
2888 = Zookeeper followers
3888= inter node connections
