Qihong Chen commented on KAFKA-7500: ------------------------------------ [~ryannedolan] Thanks for all your efforts on MM2. Appreciate your input on the following questions. I'm trying to replicate topics from one cluster to another, include topic data and related consumers' offset. But I only see the topic data was replicated, not consumer offsets. Here's my mm2.properties {code:java} clusters = dr1, dr2 dr1.bootstrap.servers = 10.1.0.4:9092,10.1.0.5:9092,10.1.0.6:9092 dr2.bootstrap.servers = 10.2.0.4:9092,10.2.0.5:9092,10.2.0.6:9092 # only allow replication dr1 -> dr2 dr1->dr2.enabled = true dr1->dr2.topics = test.* dr1->dr2.groups = test.* dr1->dr2.emit.heartbeats.enabled = false dr2->dr1.enabled = false dr2->dr1.emit.heartbeats.enabled = false {code} Here's how I started MM2 cluster (dr2 as the nearby cluster) {code:java} nohup bin/connect-mirror-maker.sh mm2.properties --clusters dr2 > mm2.log 2>&1 & {code} On dr1, there's topic *test1*, and consumer group *test1grp* for topic test1. On dr2, I found following topics {code:java} __consumer_offsets dr1.checkpoints.internal dr1.test1 heartbeats mm2-configs.dr1.internal mm2-offsets.dr1.internal mm2-status.dr1.internal {code} But couldn't find any consumer groups on dr2 related consumer group *test1grp*. Could you please let me know in detail how to migrate consumer group *test1grp* from dr1 to dr2?, i.e. what command(s) need to run to set up the offset for *test1grp* on dr2 before consume topic *dr1.test1* ? By the way, how to set up and run this in a Kafka connect cluster? i.e., how to set up MirrorSourceConnector, MirrorCheckpointConnector in a connect cluster?
