> 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
