> HMaster provides a rpc interface : 'balance()' to balance all the regions among region
servers in the cluster. Sometimes, we might want to balance all the regions belonging to a
table while keeping the region assignments of other tables. This demand may reveal in a shared
cluster where we want to balance regions for one application's table without affecting other
applications. Therefore, will it be useful if we extend the current 'balance()' interface
to only balance regions of the same table?
