从接口复制的说明: ILeaderBalancer

Generate an optimal leader distribution.

指定者:

generateOptimalLeaderDistribution 在接口中 ILeaderBalancer

参数:

regionReplicaSetMap - All RegionGroups the cluster currently have

regionLeaderMap - The current leader of each RegionGroup

disabledDataNodeSet - The DataNodes that currently unable to work(can't place RegionGroup-leader)

返回:

Map, The optimal leader distribution
