Description

Spark Connect plugins are unable to create datasets/dataframes and are unable to process relations and expressions in their planner plugins. The issue is caused by the interfaces for this in the SparkSession and the SparkConnectPlanner expect a protobuf.Any, which ends up being shaded and therefore inaccessible by the plugin.
