@VisibleForTesting
 public static void sendUserDefinedMessage(String messageSubType, String messageVal, String messageId,
   InstanceType instanceType, HelixManager helixManager, Logger logger) {
  Criteria criteria = new Criteria();
  criteria.setInstanceName("%");
  criteria.setResource("%");
  criteria.setPartition("%");
  criteria.setPartitionState("%");
  criteria.setRecipientInstanceType(instanceType);
  criteria.setSessionSpecific(true);

  Message message = new Message(Message.MessageType.USER_DEFINE_MSG.toString(), messageId);
  message.setMsgSubType(messageSubType);
  message.setAttribute(Message.Attributes.INNER_MESSAGE, messageVal);
  message.setMsgState(Message.MessageState.NEW);
  message.setTgtSessionId("*");

  int messagesSent = helixManager.getMessagingService().send(criteria, message);
  if (messagesSent == 0) {
   logger.error(String.format("Failed to send the %s message to the participants", message));
  }
 }
}
