URL: https://github.com/apache/hive/pull/3011#issuecomment-1040418854
The tests are all passing, it's the script archiving the test results
failing with `500 Internal Server Error`, not re-running just for that since
it's a waste of processing power.

> HIVE-25880 introduced a configuration parameter for excluding CBO rules based
> on a regex on their description.
> Calcite logs when a rule is excluded (see
> [AbstractRelOptPlanner.java#L316|https://github.com/apache/calcite/blob/e42b85a45bd16dd58db1546736e653deda5463fe/core/src/main/java/org/apache/calcite/plan/AbstractRelOptPlanner.java#L316]

> To ease investigations, this should be complemented by printing the regex
> used (if not blank) in Hive DEBUG logs, and the same in CBO information
> (i.e., EXPLAIN CBO's output).
