--! qt:dataset:src
-- In this test, there is a dummy stats aggregator which throws an error when various
-- methods are called (as indicated by the parameter hive.test.dummystats.aggregator)
-- Since stats need not be reliable (by setting hive.stats.reliable to false), the 
-- insert statements succeed. The insert statement succeeds even if the stats aggregator
-- is set to null, since stats need not be reliable.
