> This problem seems to only occur with reverse scan not forward scan. When
> amount of scan data is greater than SCAN_RESULT_CHUNK_SIZE(default 2999),
> Class ChunkedResultIteratorFactory will multiple calls function
> getResultIterator. But in function getResultIterator it always readjusts
> startRow, in fact, if in reverse scan we should readjust stopRow. For example
> {code:java}
> if (ScanUtil.isReversed(scan)) {
> scan.setStopRow(ByteUtil.copyKeyBytesIfNecessary(lastKey));
> } else {
> scan.setStartRow(ByteUtil.copyKeyBytesIfNecessary(lastKey));
> }
> {code}
