@Override
public Result preAppend(ObserverContext<RegionCoprocessorEnvironment> e, Append append)
  throws IOException {
 // If authorization is not enabled, we don't care about reserved tags
 if (!authorizationEnabled) {
  return null;
 }
 for (CellScanner cellScanner = append.cellScanner(); cellScanner.advance();) {
  if (!checkForReservedVisibilityTagPresence(cellScanner.current())) {
   throw new FailedSanityCheckException("Append contains cell with reserved type tag");
  }
 }
 return null;
}

@Test
public void testAppendIteration() throws IOException {
 Append a = new Append(ROW);
 for (int i = 0; i < COUNT; i++) {
  byte [] bytes = Bytes.toBytes(i);
  a.addColumn(bytes, bytes, bytes);
 }
 int index = 0;
 for (CellScanner cellScanner = a.cellScanner(); cellScanner.advance();) {
  Cell cell = cellScanner.current();
  byte [] bytes = Bytes.toBytes(index++);
  KeyValue kv = (KeyValue)cell;
  assertTrue(Bytes.equals(CellUtil.cloneFamily(kv), bytes));
  assertTrue(Bytes.equals(CellUtil.cloneValue(kv), bytes));
 }
 assertEquals(COUNT, index);
}
