Kafka MirrorMaker2 端口用于集群间通信

Question

I have setup Apache MirrorMaker 3.0.0 with active-active strategy for two Kafka clusters (named DC, DR). So topic on DC is replicated by MirrorMaker2 as DC.<topic_name> on the DR cluster and vice-vera.

In each cluster i have setup 3 kafka broker nodes.

Lets suppose below IP config is used

DC 1st node IP : kafka-dc-server1:9092
DC 2nd node IP : kafka-dc-server2:9092
DC 3rd node IP : kafka-dc-server3:9092

DR 1st node IP : kafka-dr-server1:9092
DR 2nd node IP : kafka-dr-server2:9092
DR 3rd node IP : kafka-dr-server3:9092

Connect-maker properties

DC.bootstrap.servers = kafka-dc-server1:9092, kafka-dc-server2:9092, kafka-dc-server3:9092
DR.bootstrap.servers = kafka-dr-server1:9092, kafka-dr-server2:9092, kafka-dr-server3:9092

Just want to understand whether only 9092 port is sufficient to inter cluster communication(records, offset and other metadata transition) or do we need to open connectivity on some ports also?

Answer 1

如果端口9092用作每个server.properties > listeners设置，那么，是的，这些是任何客户端通信的引导服务器值。
