QUESTION
1-The Problem
I have a Spark program that make use of Kryo but not as part of the Spark Mechanics. More specifically I am using Spark Structured Streaming connected to Kafka.
I read binary values coming from Kafka and decode it on my own.
I am faced with an Exception while attempting to deserialized Data with Kryo. This issue however only happens when I package my program and run it on a Spark Standalone Cluster. That is, it does not happen when I run it, within intellij i.e. as in Spark Local Mode (dev mode).
The exception that I get is as follow:
Caused by: com.esotericsoftware.kryo.KryoException: Unable to find class: com.elsevier.entellect.commons.package$RawData
Note that RawData is a case Class of my own, situated in one of the sub-project of my multi-project build.
To understand the context please find more details below:

I have solved that problem by picking up the "enclosing" class loader which I suppose is the one from Spark. This is after readying few comments here and there about issue with Class Loader between Kryo and Spark:
