Description

test_result_spooling.py currently runs a few basic tests with result spooling enabled. We should add some more to cover all necessary edge cases (ensure all Impala types are returned correctly, UDFs are evaluated correctly, etc.) and add tests to validate the cancellation logic in PlanRootSink.
