-----------------------------------------------------------------
[~eclark], are you saying that trunk should get this patch or this
functionality?
It seems regardless of how trunk currently implements balancing this is a valid
scenario.
Or are you saying that such control is not needed, since the balancer in trunk
will do a better job? That'd be a valid point too. :)
For 0.94 this is a simple patch. I'd \+1 for that part. But it would be strange
if 0.94 had this, but 0.96+ won't.
But it would be OK (IMHO) if the trunk balancer is just better and hence to
need to give this kind of control to the user.

> 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?
