Example 1

    throws IOException, YarnException {
  String serviceSpecFile = ServiceSpecFileGenerator.generateJson(serviceSpec);

  AppAdminClient appAdminClient =
      YarnServiceUtils.createServiceClient(clientContext.getYarnConfig());
  int code = appAdminClient.actionLaunch(serviceSpecFile,
      serviceSpec.getName(), null, null);
  if (code != EXIT_SUCCESS) {
    throw new YarnException(
        "Fail to launch application with exit code:" + code);
  }

  String appStatus = appAdminClient.getStatusString(serviceSpec.getName());
  Service app = ServiceApiUtil.jsonSerDeser.fromJson(appStatus);

  // Retry multiple times if applicationId is null
  int maxRetryTimes = 30;
  int count = 0;
  while (app.getId() == null && count < maxRetryTimes) {
    LOG.info("Waiting for application Id. AppStatusString=\n {}", appStatus);
    try {
      Thread.sleep(1000);
    } catch (InterruptedException e) {
      throw new IOException(e);
    }
    appStatus = appAdminClient.getStatusString(serviceSpec.getName());

    count++;
  }
  // Retry timeout
  if (app.getId() == null) {

        "Can't get application id for Service " + serviceSpec.getName());
  }
  ApplicationId appid = ApplicationId.fromString(app.getId());
