Github user srdo commented on the issue: https://github.com/apache/storm/pull/2560 @HeartSaVioR Thanks for reviewing. Addressed the comments. Yes, I migrated offsets from both a regular spout and a trident spout, both for a regular topic and a wildcard subscription. For the regular spout, I think it's good enough to show that the offsets a migrated to the specified consumer group, so I didn't bother setting up a storm-kafka-client spout. For Trident I set up a storm-kafka-client Trident topology and checked that the new topology picked up where the storm-kafka topology left off.
