Thank you, Ton. That helps a lot.
I want to debug spark code for tracing state transform. So I use sbt as my
build tools and compile spark code in Intellij IDEA .

Not sure what your environment is but this happened to me before because I had
a couple of servlet-api jars in the path which did not match.
I was building a system that programmatically submitted jobs so I had my own
jars that conflicted with that of spark. The solution is do mvn
