Hi, 1. It really depends on how much resources that your application need. Twill simply act as a bridge between your app and YARN, however, the YARN cluster itself needs to have enough resources (memory and vcores) to run your application.
2. You should be able to do that through the TwillRunner.lookup method. Do you mean you tried but it doesn't return anything?
