> Spark SQL currently does not support interpreted mode for all expressions and 
> projections. This is a problem for scenario's where were code generation does 
> not work, or blows past the JVM class limits. We currently cannot gracefully 
> fallback.
> This ticket is an umbrella to fix this class of problem in Spark SQL. This 
> work can be divided into two main area's:
> - Add interpreted versions for all dataset related expressions.
> - Add an interpreted version of {{GenerateUnsafeProjection}}.
