When we submit application to federation yarn cluster. Since getYarnClusterMetrics is not implemented. The submission will exit with failure.

def submitApplication(): ApplicationId = {
    ResourceRequestHelper.validateResources(sparkConf)

    var appId: ApplicationId = null
    try {
      launcherBackend.connect()
      yarnClient.init(hadoopConf)
      yarnClient.start()

     logInfo("Requesting a new application from cluster with %d NodeManagers"
          .format(yarnClient.getYarnClusterMetrics.getNumNodeManagers))
