If the test is adapted, the behavior of the merge would stay nondeterministic. For Hive histogram statistics this results in a non-deterministic behavior for the `EXPLAIN CBO JOINCOST` or also `EXPLAIN` command, see [HIVE-29334](https://issues.apache.org/jira/browse/HIVE-29334). It would be nice to add some alternative methods with the Random parameter. The behavior for the existing callers would not change. In case the caller needs deterministic merge results, they can provide a `Random` number generator with a predefined seed, though with the loss of the error guarantees. -- This is an automated message from the Apache Git Service.
