Nihal Jain commented on HBASE-21893:
------------------------------------
{quote} Observe that no data here and original snapshot size was 4 MB. but
current usage is shown as 8 MB
{quote}
Does this happen even after waiting long enough for chore to refresh usage
data? I mean does the space usage stay the same forever, given no other op
performed on table?
> Space quota: Usage is not calculated correctly if snapshot is created on a
> table then table is deleted and created again
