> Key: HIVE-17147
> URL: https://issues.apache.org/jira/browse/HIVE-17147
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Reporter: Matt McCline

>
> Current limitations:
> Only a one long key test currently. Need more tests.
> The hive-jmh test doesn't handle multiple iterations. And, the number of
> rows and keys being driven through is way too small to be meaningful.
> The focus of this change was to get things started.
> NOTE: This change does change main line code by adding test hooks.
