How to debug a java-spark application?

Is it possible to connect to a live Java-spark application and debug it using something similar to how you debug a Tomcat web service (for tomcat debug mode, for example: catalina jpda start)?

The goal is being able to attach to the java-spark micro-service and step through the source code while it's running.

Thanks!

I'd write a Junit test that calls your function / class that you want to debug, take a sample of the input data that you believe is causing the issue and make that your input. Step through the code line by line, add in lots of shows :)
