> [ErrorMSG]When start a cluster 3C3D with default config file，there is an
> error in the log of leader config node
> 重现步骤：
> 1.编译生成的distribution文件复制三份（默认配置）
> 2.进入confignode文件夹下sbin目录使用start-confignode.sh启动三个ConfigNode （正常）
> 3.进入datanode文件夹下sbin目录使用start-datanode.sh启动三个DataNode（datanode日志正常）（confignode中leader有error日志如下）
