Guanghao Zhang commented on HBASE-21618:
----------------------------------------

ProtobufUtil#toScan method will change the includeStopRow to true for old 
client which doesn't has this flag. But the new client only set this flag when 
scan.includeStopRow is true.
{code:java}
// protoScan ==> scan
if (proto.hasIncludeStopRow()) {
  includeStopRow = proto.getIncludeStopRow();
} else {
  // old client without this flag, we should consider start=end as a get.
  if (ClientUtil.areScanStartRowAndStopRowEqual(startRow, stopRow)) {
    includeStopRow = true;
  }
}

// scan ==> protoScan
if (scan.includeStopRow()) {
  scanBuilder.setIncludeStopRow(true);
}
{code}

> {code:java}
> byte[] rowkey = "some key existed";
> Scan scan = new Scan();
> scan.withStartRow(rowkey, true);
> scan.withStopRow(rowkey, false);
> htable.getScanner(scan);
> {code}
