Ted Yu commented on HBASE-12817:
--------------------------------
Integrated to master branch.
0.98 and branch-1 need separate patches.
Thanks for the patch, Duo.

> write a testcase like this
> {code}
> @Test
> public void test() throws IOException {
> for (int i = 0; i < 100; i++) {
> region.put(new Put(Bytes.toBytes("obj" + (2900 + i))).add(fam, qual1,
> Bytes.toBytes(i)));
> }
> region.put(new Put(Bytes.toBytes("obj299")).add(fam, qual1,
> Bytes.toBytes("whatever")));
> region.put(new Put(Bytes.toBytes("obj29")).add(fam, qual1,
> Bytes.toBytes("whatever")));
> region.put(new Put(Bytes.toBytes("obj2")).add(fam, qual1,
> Bytes.toBytes("whatever")));
> region.put(new Put(Bytes.toBytes("obj3")).add(fam, qual1,
> Bytes.toBytes("whatever")));
> region.flushcache(true);
> Scan scan = new Scan(Bytes.toBytes("obj29995"));
> RegionScanner scanner = region.getScanner(scan);
> List<Cell> cells = new ArrayList<Cell>();
> assertFalse(scanner.next(cells));
> assertArrayEquals(Bytes.toBytes("obj3"), Result.create(cells).getRow());
> }
> {code}
> use obj29995 to scan should return obj3, but obj2990 is returned.
> Seems a bug introduced by the fix of HBASE-11728.
