    while (excessWorkload > 0) {
      Integer availableCapacity=availableNodeCapacity();
      if (availableCapacity <= 0) {
        LOGGER.warning(String.format("String_Node_Str",excessWorkload,getCloudName(),getInstanceCap()));
        break;
      }
      final ComputeEngineInstance node=config.provision(StreamTaskListener.fromStdout(),label);
