> Before https://issues.apache.org/jira/browse/HIVE-20915 , the optimizer sort dynamic
partitions is turn off for these tests. So these test can have group by in the query plan
which can trigger compute statistics. After the jira, the optimizer is enabled, because of
a a known bug with dynamic sorted partition optimization (HIVE-16100), the computer statistics
does not happen. Fix the tests to disable the optimizer to test the same code path as before.
