-----------------------------------

I think this is fine. The master is going to execute region split plan which
would result in increment of region count for the underlying table.
{quote}
I have two questions:
* could we handle split plan failed if we update quota info here?
* If we update quota info when plan type is split, should we update quota
when split plan is merge?
> Region normalization should be allowed when underlying namespace has quota

> Currently when namespace has quota, HMaster#normalizeRegions() skips the
> tables in the namespace.
> However, performing region merge(s) wouldn't violate quota constraint.
> For region split, NamespaceAuditor#checkQuotaToSplitRegion() can be called to
> check whether quota is about to be exceeded. If not, region split plan can
> still be executed.
