Storm Topology 提交总结---Kettle On Storm 实现

一，目的在学习的过程中，需要用到PDI---一个开源的ETL软件。主要是用它来设计一些转换流程来处理数据。但是，在PDI中设计好的transformation是在本地的执行引擎中执行的，(参考源码中的Trans.java)，现可以对DI加以改造：在DI中设计的转换，将之转换成Storm的Topology，然后再把该To...

Storm WordCount Topology学习

1，分布式单词计数的流程首先要有数据源，在SentenceSpout中定义了一个字符串数组sentences来模拟数据源。字符串数组中的每句话作为一个tuple发射。其实，SplitBolt接收SentenceSpout发射的tuple，它将每句话分割成每个单词，并将每个单词作为tuple发射。再次，WordCount...
