kafka分区leader切换

Question

kafka+storm构架
kafka 版本kafka_2.10-0.8.2.1，topic 副本数为2。zk版本3.4.6，storm版本apache-storm-0.9.4

近期storm消费总发现下面这样的报错：storm.kafka.FailedFetchException: Error fetching data from [Partition{host=xx.xx.xx.xx:9092, partition=11}] for topic [test]: [NOT_LEADER_FOR_PARTITION] at storm.kafka.KafkaUtils.fetchMessages
通过kafka-topics.sh --zookeeper localhost --describe，发现主从分区总有切换，如原本partition 0的leader 为broker 1，会变为broker 2。查看kafka日志，发现了下面的信息，但是没看太明白，网上也没找到解决办法。有没有人遇到过类似的情况？

感觉应该是在某个broker down掉后，从分区接手时才应该切换。但是broker并没有down

Answer 1

晕倒，我的是broker 宕掉后，重新起来就这样了。大师救救俺吧！

Answer 2

你好，这个问题解决了么？是不是应为依赖的jar的问题？
