com.linkedin.helix.ClusterMessagingService.sendAndWait()
This will send the message to all instances matching the criteria
When there is a reply to the message sent AsynCallback.onReply will be invoked. Application can specify a timeout on AsyncCallback. After every reply is processed AsyncCallback.isDone will be invoked.
This method will return only after the AsyncCallback.isDone() returns true
This is useful when message need to be sent and current thread has to wait for response.
The current thread can use callbackOnReply instance to store application specific data. @param receipientCriteria @param message @param callbackOnReply @param timeOut @param retryCount @return

      recipientCriteria.setSessionSpecific(true);
      // wait for 30 seconds
      int timeout = 30000;
      BootstrapReplyHandler responseHandler = new BootstrapReplyHandler();


      int sentMessageCount = messagingService.sendAndWait(recipientCriteria,
          requestBackupUriRequest, responseHandler, timeout);
      if (sentMessageCount == 0)
      {
        // could not find any other node hosting the partition
      } else if (responseHandler.getBootstrapUrl() != null)
