> our row key is combined with two ints, and we found that sometimes when we
> using only the first int part to scan, the result returned may missing some
> rows. But when we dump the whole hfile, the row is still there.
> We have written a testcase to reproduce the bug. It works like this:
> put 1-12345
> put 12345-0x01000000
> put 12345-0x01010000
> put 12345-0x02000000
> put 12345-0x02020000
> put 12345-0x03000000
> put 12345-0x03030000
> put 12345-0x04000000
> put 12345-0x04040000
> flush memstore
> then scan using 12345，the returned row key will be
> 12345-0x20000000(12345-0x10000000 expected)
