------------------------------------
Summary: Use objects and abstract classes in for Kind and
SessionState.
Key: LIVY-415
URL: https://issues.apache.org/jira/browse/LIVY-415
Project: Livy
Issue Type: Improvement
Reporter: Arun Allamsetty
Priority: Trivial
Scala lets us define Singleton Objects
(https://docs.scala-lang.org/tour/singleton-objects.html) rather than creating
(case) classes and which just have a default constructor. Also, using abstract
classes helps with brevity in this case as we can assign default definitions to
the functions we need.
