萨蒂什，
对于您看到的问题，添加/删除服务可能导致了问题。当服务发生变化时，bluemix-settings.js有时无法正确同步，您需要下载源代码，更新源代码，并将应用程序推上备份。如果你刚刚开始创建应用程序，我建议你从零开始删除模板，然后创建新的应用程序。这将解决任何问题。
下面是一个简单的例子，分析twitter数据时不需要一行代码，也不需要添加任何超出创建node红色样板文件时添加的服务：link to developer works文章。

萨蒂什，
从node red starter样板文件进行部署似乎有问题。我只是尝试了一下，也失败了，当我检查日志时，我发现有一个错误，需要有人调查，所以我在几分钟前打开了一张这方面的罚单。
无论如何，即使部署可以工作，您也无法完成教程：自从romeo编写了它之后，analytics for hadoop服务已经升级。教程的一部分已经不正确了，上一次我检查了bluemix上node red中的hdfs节点有一个问题，它无法再连接到hadoop。
你好，哈罗德

萨蒂什，
尝试使用apachehadoop分析服务。hdfs节点的最新修复应该会有所帮助。我附上红色节点源供您参考。

在部署流之前绑定/添加服务。
