java连接ranger+ldap认证的hive

        使用java连接ranger+ldap认证的hive，通过jdbc加上用户名密码即可，代码示例如下：

import java.sql.*;

public class JdbcHiveLdap {

    private static String driverName = "org.apache.hive.jdbc.HiveDriver";

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

        try {

            Class.forName(driverName);

        } catch (ClassNotFoundException e) {

            e.printStackTrace();

            System.exit(1);

        }
// Hive2 JDBC URL with LDAP

        String jdbcURL = "jdbc:hive2://ip:10000/default";

        Connection conn = DriverManager.getConnection(jdbcURL,"username","password");

        PreparedStatement ps = conn.prepareStatement("show databases");
        ResultSet rs = ps.executeQuery();
        while (rs.next()) {
            System.out.println("hive数据库："+rs.getString(1));
        }
        conn.close();

    }

}
