Hive JDBC连接hive（2.1.1）(需要ssl认证)（java）

Hive JDBC连接hive（2.1.1）（java）

1.Maven 依赖

 <dependencies>
        <!--hive jdbc依赖 此包有签名需要排除他们-->
        <dependency>
            <groupId>org.apache.hive</groupId>
            <artifactId>hive-jdbc</artifactId>
            <version>2.1.1-cdh6.3.0</version>
        </dependency>

    </dependencies>

2.kerberos 或者LDAP认证

LDAP认证

代码如下：

public class HIveJDBC {

    private static String driverName = "org.apache.hive.jdbc.HiveDriver";
    private static String HIVE_URL = "jdbc:hive2://cdh-master03:25005/zyh;ssl=true;sslTrustStore=D:/cdh/hive/src/main/ssl/cm-auto-global_truststore.jks;";
    private static String user = "gree1";
    private static String password = "000000";

    public static void main(String[] args) throws Exception {

        Class.forName(driverName);

        Connection conn = DriverManager.getConnection(HIVE_URL, user, password);

        Statement st = conn.createStatement();

        ResultSet resultSet = st.executeQuery("select  * from zhchivetable");

        while (resultSet.next()) {
            System.out.println(resultSet.getString(1));
        }
    }
}

kerberos 认证

import hivekerberosauth.KuduKerberosAuth;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

/**
 * 用于通过hive jdbc 连接hive 测试
 */

public class HIveJDBC {

    private static String driverName = "org.apache.hive.jdbc.HiveDriver";
       private static String CONNECTION_URL ="jdbc:hive2://cdh-master03:25005/;ssl=true;sslTrustStore=D:/cdh/hive/src/main/ssl/cm-auto-global_truststore.jks;principal=hive/cdh-master03@GREE.IO";

    public static void main(String[] args) throws Exception {
        KuduKerberosAuth.initKerberosENV(false);

        Class.forName(driverName);

        Connection conn = DriverManager.getConnection(CONNECTION_URL);

        Statement st = conn.createStatement();

        ResultSet resultSet = st.executeQuery("select  * from zyh.zhchivetable");

        while (resultSet.next()) {
            System.out.println(resultSet.getString(1));
        }
    }

}

import org.apache.hadoop.security.UserGroupInformation;

public class KuduKerberosAuth {

    /**
     * 初始化访问Kerberos访问
     * @param debug 是否启用Kerberos的Debug模式
     */
    public static void initKerberosENV(Boolean debug) {
        try {
            System.setProperty("java.security.krb5.conf","D:\cdh\hive\src\main\kerberos\krb5.conf");
//            System.setProperty("java.security.krb5.conf","/lvm/data3/zhc/krb5.conf");
            System.setProperty("javax.security.auth.useSubjectCredsOnly", "false");
            if (debug){
                System.setProperty("sun.security.krb5.debug", "true");
            }
             UserGroupInformation.loginUserFromKeytab("gree1@GREE.IO", "D:\cdh\hive\src\main\kerberos\gree1.keytab");
//            UserGroupInformation.loginUserFromKeytab("gree1@GREE.IO", "/lvm/data3/zhc/gree1.keytab");
             System.out.println(UserGroupInformation.getCurrentUser());
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
}
