hi all we have 20 kafka brokers in on cluster. and this morning, we cannot find one kafka broker when using "kafka-topic.sh" to get topic information.
we find lots of error: "[2016-05-18 09:59:59,998] ERROR [ReplicaFetcherThread-0-1005], Error for partition [0000000033,58] to broker 1005:class kafka.common.NotLeaderForPartitionException (kafka.server.ReplicaFetcherThread)" in server.log in the wrong status broker. this broker is running always and the state-change.log is clear. finnaly, we restart this broker and it works. who can explain this scene? what's the reason?
