------------------------------------------
Summary: Exclude Category-X JDBC drivers from binary distribution
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
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.
