-------------------------------------------------------------
Problem is:
1: Initially usage was 8 MB , so any data write will fail at that time because
no quota violation policy is 5 MB.
2: This 4 MB data belongs to old table and not the new table which was created
later. So earlier created snapshot data should not be used to calculate usage
of new table.

Problem is:
1: Initially usage was 8 MB , so any data write will fail at that time because
no quota violation policy is 7 MB.
2: This 4 MB data belongs to old table and not the new table which was created
later. So earlier created snapshot data should not be used to calculate usage
of new table.
> Space quota: Usage is not calculated correctly if snapshot is created on a
> table then table is deleted and created again

> *Steps to reproduce:*
> 1: ./hbase pe --table="bugatti" --nomapred --rows=400 sequentialWrite 10
> (will put 4 mb data)
> 2: set_quota TYPE => SPACE, TABLE => 'bugatti', LIMIT => '7M', POLICY =>
> NO_WRITES_COMPACTIONS
> 3: snapshot 'bugatti','bugatti_snapshot'
> 4: disable 'bugatti'
> 5: drop 'bugatti'
> 6: create 'bugatti','info0'
> 7: set_quota TYPE => SPACE, TABLE => 'bugatti', LIMIT => '5M', POLICY =>
> NO_WRITES_COMPACTIONS
> 8: scan 'bugatti'
> >> Observe that no data here and original snapshot size was 4 MB. but current
> >> usage is shown as 8 MB
