Install Python 2.7 and Node.js (version >= 6)
Open terminal in folder './AxtriaWorkbench/'
Install impyla

pip install impyla

Start express server

npm start

Open the Cloudera cluster, then open chrome browser and go to http://localhost:3000 (Now you should see the webpages)

Usage

Login: default username & password: admin / admin (You can also register a new one)
By default, you should be at the query page. The first thing to do is setting up parameters in all five questions.
Click 'Submit' and now you should be directed to the report page. Since the query needs some time to run, you have to wait until the results are fetched (DO NOT CLOSE OR REFRESH!). After that, all the results will be displayed automatically.
Select 'COHORT' or 'KICKOUT' tab, and click 'Download CSV' to download the data as a csv file.
Click Logout to exit.

How to modify

If you'd like to add more queries, you need to modify 3 files. First, add more questions in the query.html. Second, go to app.js and add corresponding data and send query using socket. Third, display data in the report.html using ng-repeat.

Also, if you want to implement data visualization on the graph page, make sure to add a new route in app.js, and make graph.html a div only rather than a complete html.
