Hi Shen, Arff files are text files (fancy csv with a header). What do you mean with "process text files"? You need a way to convert a text file into structured data, arff is one way to do that.
Which version of Storm are you using? We have run experiments on Storm clusters, and they usually work, however there might be configuration issues.
