Hi, I have 3 Kafka nodes (running 0.9.0) that all had active consumers and producers.
Now all these had uncompacted __consumer_offsets group that grew to 1.8 TB. So I restarted these nodes with a log.cleaner.enabled to save some space. Since then consumers have stalled. When I do a ./kafka-consumer-groups.sh kafka-groups.sh --zookeeper 10.211.16.215 --group groupX --describe, I get "Could not fetch offset from kafka for group GroupX partition [GroupX, 0] due to kafka.common.NotCoordinatorForConsumerException". Note that the compaction is still in progress. And I get this for most consumer groups. Any clues how to fix this ? Regards, Sathya
