------------------------------------------
> Add explicit dependency to commons-dbcp2 in hive-exec module
> ------------------------------------------------------------

> Key: HIVE-26458
> URL: https://issues.apache.org/jira/browse/HIVE-26458
> Project: Hive
> Issue Type: Task
> Reporter: Stamatis Zampetakis

> Priority: Major

> Hive CBO relies on Calcite so there is a direct dependency towards Calcite in
> hive-exec module. On its turn, Calcite needs commons-dbcp2 dependency in
> order to compile and run properly:
> https://github.com/apache/calcite/blob/b9c2099ea92a575084b55a206efc5dd341c0df62/core/build.gradle.kts#L69
> In particular the dependency is necessary in order to use the JDBC adapter
> and some of its usages are shown below:

> However, due to the [shading of
> Calcite|https://github.com/apache/hive/blob/778c838317c952dcd273fd6c7a51491746a1d807/ql/pom.xml#L1075]
> inside hive-exec module all the transitive dependencies coming from Calcite
> must be defined explicitly otherwise they will not make it to the classpath.
> At the moment this does not pose a problem in master since {{commons-dbcp2}}
> dependency comes transitively from other modules. But in certain Hive
> branches with slightly different dependencies between modules we have seen
> failures like the one shown below:
