Hm, tricky. You don't have the scan the whole table - just the last
region. You can find out what the start key of the last region is by
using HTable#getStartKeys. If this isn't an acceptable solution, we
might be able to think up a way to get the last real row of a table
more efficiently.
Actually, I need to obtain the 3333 rows starting from the last row
rather than the first row.
So I wonder is it possible to obtain a scanner that scan in the reverse
direction.
I.e. Starting from the last row to the first row.

Hi
I want to find out the maximum value of the row id of a table.
Is there a simple and efficient way to do this without scan through the
whole table starting from the first row?
Thanks.
