官方文档

解决方案

  1. Increase group.max.size on the broker via kafka-configs.sh:
kafka-configs.sh --bootstrap-server localhost:9092 --entity-type brokers --entity-default --alter --add-config group.max.size=20
  2. Reduce the number of consumer instances in the group by consolidating partitions to fewer consumers.

无效尝试

常见但无效的做法:

  1. 95% 失败

    Restarting consumers individually does not resolve the underlying configuration limit.

  2. 90% 失败

    Deleting offsets only resets consumption progress, not the group membership count.
