--! qt:dataset:src
-- In this test, there is a dummy stats publisher which throws an error when the
-- method connect is called (as indicated by the parameter hive.test.dummystats.publisher)
-- If stats need not be reliable, the statement succeeds. However, if stats are supposed
-- to be reliable (by setting hive.stats.reliable to true), the insert statement fails
-- because stats cannot be collected for this statement
