[異常處理]class kafka.common.UnknownTopicOrPartitionException (kafka.server.ReplicaFetcherThread)

在kafka.out日志裡出現大量

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

這是由于删除topic沒删幹淨

在zookeeper裡删除下列路徑下的資料：

/brokers/topics/[topic]

/consumers/[groupId]/owners/[topic]

/consumers/[groupId]/offsets/[topic]

重新開機kafka叢集
