> Nicolas pointed out to me that the new unit test TestMultiColumnScanner that
> I wrote for the multi-column scanner Bloom filter optimization (which we will
> soon release) did not pass on the open-source trunk, and it bisected down to
> the HFile v2 commit. I debugged the unit test and found that there was a
> serious bug in HFile v2 Bloom filter lookup not caught by any of the existing
> unit tests: Bloom filters were used for "non-Get" Scans, which did not have
> minimum/maximum row set correctly, and some scan results were not returned.
> This diff is the unit test that helped catch the problem and a one-line fix
> for the bug.
