I am debug spark (itself not its application) by running `sbt default test suite`. I have successfully set up everything, and IntelliJ debugger have caught every variables. However, I can not find the variables I need, because there are so many variables.
For example, I want to find the input data frame, the transformed data frame, and the output data frame. Where should I look at?
What I tried:
1. use search function in IntelliJ to search variable name.
