Liu Junhong commented on HBASE-12713:
-------------------------------------

Yes,but sometimes i should disable the load balancer. This policy is not applicable this
case?

> I find that the policy of region split which in IncreasingToUpperBoundRegionSplitPolicy
will be use the value of "maxfilesize" when the count of region is greater than 100. But sometimes
100 regions is not too much for a cluster that has 50 or more regionservers.
> So i think this policy should consider the density of the regions but not the total count
of the regions.
