One way to address this:
- Create a trait
ExecutionContextwith necessary APIs - make
DataFrameholdBox<dyn ExecutionContext>
This allows DataFusions' DataFrame to have different contexts resolved at run time (e.g. whether local or cluster is passed?).

I am closing this since I found a different solution to this issue. Ballista uses the DataFusion context but provides its own query planner which results in a DistributedQueryExec physical plan, so DataFrame.collect() invokes that.
