场景：kafka配置文件log.dirs增加了几个目录，但是新目录没有分区数据写入，所以打算进行重分区一下。

1.生成迁移计划

进入kafka/bin目录

新建 topic-reassign.json,把要重分区的topic按下面格式写。

{
          "topics": [{
                       "topic": "VOLTE_GM"
                    },{
                       "topic": "VOLTE_GM_MEDIA"
                    },{
                       "topic": "VOLTE_MW"
                    },{
                       "topic": "VOLTE_RX"
                    },{
                       "topic": "VOLTE_SH"
                    },{
                       "topic": "VOLTE_SV"
                    }],
          "version": 1
}

执行命令

./kafka-reassign-partitions.sh --zookeeper kafka001:2181/kafka --generate --topics-to-move-json-file topic-reassign.json --broker-list 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39

broker-list 是kafka配置文件中的 broker.id

输出：

Current partition replica assignment：当前分区策略，建议保存，回退的时候会用到。

Proposed partition reassignment configuration：建议分区策略

Proposed partition reassignment configuration

将标红的json保存到topic-todo.json

2.执行迁移命令
