> Umbrella issue for tracking the filesystem utilization of HBase data, defining quotas
on that utilization, and enforcement when utilization exceeds the limits of the quota.
> At a high level: we can define quotas on tables and namespaces. Region size is computed
by RegionServers and sent to the Master. The Master inspects the sizes of Regions, rolling
up to table and namespace sizes. Defined quotas in the quota table are evaluated given the
computed sizes, and, for those tables/namespaces violating the quota, RegionServers are informed
to take some action to limit any further filesystem growth by that table/namespace.
