Stamatis Zampetakis commented on HIVE-25832:
--------------------------------------------
Personally, I would prefer that we don't distribute any JDBC drivers as part of
Hive but instruct people to install the appropriate one based on the underlying
DBMS they use but this may deserve a bigger discussion so not considering this
now.
Moreover, I was surprised that dependencies marked as optional (such as the
JDBC drivers) make it to the package distribution. This is done by the Maven
Assembly plugin and might change in the future (see MASSEMBLY-832).

> Key: HIVE-25832
> URL: https://issues.apache.org/jira/browse/HIVE-25832
> Project: Hive
> Issue Type: Task
> Components: distribution
> Reporter: Stamatis Zampetakis
> Assignee: Stamatis Zampetakis
> Priority: Major
>
> The binary distribution contains all the required elements to be able to run
> Hive in a cluster. It can be obtained by building from source using the
> following command:
> {code:java}
> mvn clean package -DskipTests -Pdist{code}
> The binary distribution is also published during a release along with the
> source code.
>
> In current master, commit 8572c1201e1d483eb03c7e413f4ff7f9b6f4a3d2, the
> binary distribution includes the following JDBC drivers:
> * derby-10.14.1.0.jar
> * postgresql-42.2.14.jar
> * ojdbc8-21.3.0.0.jar
> * mssql-jdbc-6.2.1.jre8.jar
> * mysql-connector-java-8.0.27.jar
> JDBC drivers are needed:
> * by schemaTool to initialize the database backend for the Metastore
> * by metastore to communicate with underlying database
> so if we want Hive to work out of the box we have to provide at least one.
> The Oracle (ojdbc8) and MySQL (mysql-connector-java) drivers must be removed
> cause their license is not compatible with Apache License 2 (see [category
> x|https://www.apache.org/legal/resolved.html#category-x]).
> Previous Hive releases (e.g., 3.1.2) are not affected since they only contain:
> * derby-10.14.1.0.jar
> * postgresql-9.4.1208.jre7.jar
> The additional drivers that appear in the binary distribution are a side
> effect of HIVE-25701.
