             Summary: Introduce Shim for missing spark/core classes
                 Key: SPARK-49569
                 URL: https://issues.apache.org/jira/browse/SPARK-49569
             Project: Spark
          Issue Type: New Feature
          Components: Connect, SQL
    Affects Versions: 4.0.0
            Reporter: Herman van Hövell


Introduce shims for SparkContext, RDD, and QueryExecution. This will have to be 
a in a separate module, and is supposed to be a compile time dependency for 
sql/api project, and an actual dependency for an independent Spark Connect 
Client.

We need these three classes to support all user facing API in the sql/api 
project. This will allow us to make the classes the primary interface for Scala 
Dataset operations.

For connect these methods will throw an (actionable) error, and for the classic 
client they will just work. On the connect side in the future we can use this 
to build better errors, and provide (method specific) mitigations.
