---------------------------------------
Summary: add negative tests
Key: HIVE-20029
URL: https://issues.apache.org/jira/browse/HIVE-20029
Project: Hive
Issue Type: Sub-task
Reporter: Sergey Shelukhin
We need a few tests, esp. for parallel case, where we verify that stats are NOT
used.
Right now many code paths don't fail but return -1, null or whatever when
something else is not present, so positive tests might pass because they skip
the check, not because the check passes.
