> Space Quota: Space Quota Issue: If a table is created with region replica
> then quota calculation is not happening
> Steps:
> 1: Create a table with 100 regions with region replica 3
> 2: Observe that 'hbase:quota' table doesn't have entry of usage for this
> table So In UI only policy Limit and Policy is shown but not Usage and State.
> Reason:
> It looks like File system utilization core is sending data of 100 reasons
> but not the size of region replicas.
> But in quota observer chore, it is considering total region(actual regions+
> replica reasons)
> So the ratio of reported regions is less then configured
> percentRegionsReportedThreshold.
> SO quota calculation is not happening
