在kafka.out日志里出现大量

ERROR [ReplicaFetcherThread-0-1], Error for partition [FLAG_DATA_SYC,1] to broker 1:class kafka.common.UnknownTopicOrPartitionException (kafka.server.ReplicaFetcherThread)


这是因为删除topic没删干净

在zookeeper里删除下列路径下的数据:
/brokers/topics/[topic]
/consumers/[groupId]/owners/[topic]
/consumers/[groupId]/offsets/[topic]

重新启动kafka集群
