> Remove Druid integration
> ------------------------

> Key: HIVE-29745
> URL: https://issues.apache.org/jira/browse/HIVE-29745
> Project: Hive
> Issue Type: Task
> Components: Druid integration
> Reporter: Stamatis Zampetakis
> Assignee: Stamatis Zampetakis
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.3.0

>
> The Druid integration is broken at least since 2021 (and maybe before). More
> than 5 years have passed and nobody complained or attempted to fix it.
> Moreover, the 0.17.1 Druid version used in the project is very old and
> incompatible with many core dependencies such as Calcite, Avatica, Jackson,
> Derby, etc. By keeping Druid we accumulate tech-debt and many CVEs for a
> feature that is broken and apparently unused.
