> 3副本1C4D，迁移region的Id=1 ，这个region的信息是1个副本是Running，1个是Unkown，1个是ReadOnly，迁移失败。
> 1.迁移开始前，查看region信息

> 2.迁移命令
> ./sbin/start-cli.sh -h 172.20.70.4 -e "migrate region 1 from 1 to 3"
> 命令返回成功
> 3.实际迁移失败，ConfigNode日志报错
> !image-2022-12-29-17-17-26-853.png|width=1286,height=291!
> 迁移失败后，再执行一遍命令，会报目标节点已存在迁移region，实际上，并不存在。

> DataNode配置
> MAX_HEAP_SIZE="20G"
> MAX_DIRECT_MEMORY_SIZE="6G"
> dn_max_connection_for_internal_service=300
> ConfigNode配置
> MAX_HEAP_SIZE="20G"
> MAX_DIRECT_MEMORY_SIZE="6G"
> 运行BM写入数据，全部写入成功。
> 再执行stop datanode和set system to readonly on local的操作。
