List, Documentation about Group Coordinator election seems to reference zookeeper, but I am unable to find anything in zookeeper. Is it using kafka to store this information like consumer offsets ?
Can someone explain how Group Coordinator election works ? We had an incident during a reassignment of partitions. One consumer group, for ~15 mins, was unable to discover their coordinator and kept retrying the ConsumerMetadataRequest rpc. Any pointers to code and accurate documentation would be welcome. thanks!
