Hadoop學習筆記（十九）---Hive Java Api

1。首先要啓動hive的服務器：

hive --service hiveserver &

hive默認的端口爲：10000

2.程序源代碼爲：

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


public class HiveTest {

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

        Class.forName("org.apache.hadoop.hive.jdbc.HiveDriver");
        Connection conn = DriverManager.getConnection("jdbc:hive://hadoop0:10000/default","","");
        Statement stmt = conn.createStatement();
        String querySql = "select * from stu";
        ResultSet rs = stmt.executeQuery(querySql);

        while(rs.next()) {
            System.out.println(rs.getInt(1));
        }

        rs.close();
        stmt.close();
        conn.close();

    }

}
