> Key: KAFKA-12169
> URL: https://issues.apache.org/jira/browse/KAFKA-12169
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Affects Versions: 2.5.1, 2.6.1
> Reporter: zou shengfu
> Priority: Major
> Labels: bug, new-rebalance-should-fix
>
> Background:
> Kafka consumer services run with static membership and cooperative rebalance
> protocol on kubernetes, and services often restart because of operation. When
> we added partitions from 1000 to 2000 for the topic, client leader restart
> with unknown member id at the same time, we found the consumers do not
> tigger rebalance and still consume 1000 paritions
