Hi, Thanks for your reply, after some reading of the wiki pages, I think what I want is a Logistic Regression command-line, since the target users of Mahout are data analysts, who can't write Java code, a command line is more convenient. Some specific questions are : 1. What format should we apply when preparing data for logistic regression, can we use csv, and should we put the value for the target variable as the first column in every row the csv file. 2. What options can we support to the command line if there is one. 3. How can interpret the results.
Because Logistic Regression is the working horse of credit scoring in industry, I think it will make Mahout friends of more analysts if LR support is smooth.

Can you be more specific about what you have and what you want? The book Mahout in Action provides quite a lot of details with sample code for a server farm. The TrainNewsGroups example provides code that you can copy. Do you have these resources? Do you want more? Did you want more theory?
