cuijianwei commented on HBASE-10127:
------------------------------------
Thanks for your comment [~lhofhansl]. I go through the logic of 'balance()' and
try the patch in our cluster, the balancing result seems good. I will take a
close look at the logic of 'balance()'. On the other hand, if there is a
specific issue where the resulting balancing was bad, I think we might need to
fix the problem because bad cluster balancing result may also be generated if
there is only one table in the cluster.

> 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?
