@Override

    final Put put, final WALEdit edit, final Durability durability)

  User user = getActiveUser();
  checkForReservedTagPresence(user, put);

  // Require WRITE permission to the table, CF, or top visible value, if any.
  // NOTE: We don't need to check the permissions for any earlier Puts
  // because we treat the ACLs in each Put as timestamped like any other
  // HBase value. A new ACL in a new Put applies to that Put. It doesn't
  // change the ACL of any previous Put. This allows simple evolution of
  // security policy over time without requiring expensive updates.
  RegionCoprocessorEnvironment env = c.getEnvironment();
  Map<byte[],? extends Collection<Cell>> families = put.getFamilyCellMap();
  AuthResult authResult = permissionGranted(OpType.PUT, user, env, families, Action.WRITE);
  logResult(authResult);
  if (!authResult.isAllowed()) {
    if (cellFeaturesEnabled && !compatibleEarlyTermination) {
      put.setAttribute(CHECK_COVERING_PERM, TRUE);
    } else if (authorizationEnabled) {
      throw new AccessDeniedException("Insufficient permissions " + authResult.toContextString());
    }
  }

  // Add cell ACLs from the operation to the cells themselves
  byte[] bytes = put.getAttribute(AccessControlConstants.OP_ATTRIBUTE_ACL);
