一、POM文件引入的依賴如下：

1、此處hadoop-common和hive-jdbc都需要排除servlet-api，否則將出現springboot啟動報錯，例如：‘unable to start embedded tomcat‘ 或者 ‘A child container failed during start‘

2、使用hive-jdbc其它版本並執行第二點中的代碼時，可能出現protocl-client過時並連接不上的問題

二、JDBC連接的代碼

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.security.UserGroupInformation;

import java.sql.*;

public class Test {

    public static void main(String[] args) throws Exception {
        // 解決windows中執行可能出現讀不到krb5配置文件的問題
        System.setProperty("java.security.krb5.conf", "C:/kerberos/test/config/krb5.conf");
        
 
// 解決window中執行可能出現找不到HADOOP_HOME或hadoop.home.dir問題
        System.setProperty("hadoop.home.dir", "C:\\Program Files\\winutils-master\\hadoop-2.8.3");
        // Kerberos認證
        Configuration configuration = new Configuration();
        configuration.set("hadoop.security.authentication", "Kerberos");
        configuration.set(
 
"keytab.file" , "C:/kerberos/test/config/hadoop.keytab" );
        configuration.set("kerberos.principal" , "[email protected]" );        
        UserGroupInformation.setConfiguration(configuration);
        UserGroupInformation.loginUserFromKeytab("[email protected]", "C:/kerberos/test/config/hadoop.keytab");
        // 創建hive連接
        Connection connection = null;
        ResultSet rs = null;
        PreparedStatement ps = null;
        try {
            Class.forName("org.apache.hive.jdbc.HiveDriver");
            connection = DriverManager.getConnection("jdbc:hive2://bdpnode1.domain.com:10000/;principal=hive/[email protected]COM","hadoop","");
            if (null != connection) {
                ps = connection.prepareStatement("SELECT * FROM test");
                rs = ps.executeQuery();
                while (rs.next()) {
                    System.out.println(rs.getInt(1));
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (rs != null) {
                rs.close();
            }
            if (ps != null) {
                ps.close();
            }
            if (connection != null) {
                connection.close();
            }
        }
    }
}

springboot 1.5.6 + jdbc使用kerberos認證方式連接hive
