问题背景与现象

新建Kafka集群,部署Broker节点数为2,使用Kafka客户端可以正常生产,但是无法正常消费。Consumer消费数据失败,提示GROUP_COORDINATOR_NOT_AVAILABLE,关键日志如下:

2018-05-12 10:58:42,561 | INFO | [kafka-request-handler-3] | [GroupCoordinator 2]: Preparing to restabilize group DemoConsumer with old generation 118 | kafka.coordinator.GroupCoordinator (Logging.scala:68)
