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)
这是由于删除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]
重启kafka集群
