Getting Started with Hive JDBC
==============================

How to get the Kyuubi JDBC driver
---------------------------------

Kyuubi Thrift API is fully compatible with HiveServer2, so technically, it allows to use any Hive JDBC driver to connect
Kyuubi Server. But it's recommended to use :doc:`../client/jdbc/kyuubi_jdbc`, which is forked from
Hive 3.1.x JDBC driver, aims to support some missing functionalities of the original Hive JDBC driver.

The driver is available from Maven Central:

.. parsed-literal::

<dependency>
<groupId>org.apache.kyuubi</groupId>
<artifactId>kyuubi-hive-jdbc-shaded</artifactId>
<version>\ |release|\</version>
</dependency>


Connect to non-kerberized Kyuubi Server
---------------------------------------

The following java code connects directly to the Kyuubi Server by JDBC without using kerberos authentication.

.. code-block:: java

package org.apache.kyuubi.examples;

import java.sql.*;

public class KyuubiJDBC {

private static String driverName = "org.apache.kyuubi.jdbc.KyuubiHiveDriver";
private static String kyuubiJdbcUrl = "jdbc:kyuubi://localhost:10009/default;";

public static void main(String[] args) throws SQLException {
try (
Connection conn = DriverManager.getConnection(kyuubiJdbcUrl);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("show databases")) {
while (rs.next()) {
System.out.println(rs.getString(1));
}
}
}
}

Connect to Kerberized Kyuubi Server
-----------------------------------

The following Java code uses a keytab file to login and connect to Kyuubi Server by JDBC.

.. code-block:: java

package org.apache.kyuubi.examples;

import java.sql.*;

public class KyuubiJDBCDemo {

private static String driverName = "org.apache.kyuubi.jdbc.KyuubiHiveDriver";
private static String kyuubiJdbcUrlTemplate = "jdbc:kyuubi://localhost:10009/default;" +
"kyuubiClientPrincipal=%s;kyuubiClientKeytab=%s;kyuubiServerPrincipal=%s";

public static void main(String[] args) throws SQLException {
String clientPrincipal = args[0]; // Kerberos principal
String clientKeytab = args[1]; // Keytab file location
String serverPrincipal = args[2]; // Kerberos principal used by Kyuubi Server
String kyuubiJdbcUrl = String.format(kyuubiJdbcUrlTemplate, clientPrincipal, clientKeytab, serverPrincipal);
try (
Connection conn = DriverManager.getConnection(kyuubiJdbcUrl);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("show databases")) {
while (rs.next()) {
System.out.println(rs.getString(1));
}
}
}
}
