1.啟動hiveserver2

nohup /home/hadoop/hive-1.1.0-cdh5.5.2/bin/hiveserver2 >> /home/hadoop/gtq_dir/logs/hiveserver.log 2>&1 &

2.代碼如下：

package cn.hive;

import java.sql.*;

/**
 * Created by jieyue on 2017/12/18.
 */
public class HiveJdbcTest {
    private static String driveName = "org.apache.hive.jdbc.HiveDriver";
    
 
private static Connection con = null;
    private static Statement stmt = null;
    private static ResultSet res = null;

    public static void main(String[] args) throws SQLException {
        try {
            Class.forName(driveName);
            con = DriverManager.getConnection("jdbc:hive2://172.17.101.12:10000/demo", "root", "");
            stmt 
 
= con.createStatement();
            String tableName = "t_h_jdbc";
            stmt.execute("DROP TABLE IF EXISTS " + tableName);
            stmt.execute("create table " + tableName + "(key int ,value string)");
            System.out.println("create table success!!");

            String sql = "show create table " + tableName;
            System.out.println(
 
"Running :" + sql);
            res = stmt.executeQuery(sql);
            if (res.next()) System.out.println(res.getString(1));

            sql = "desc " + tableName;
            System.out.println("Running :" + sql);
            res = stmt.executeQuery(sql);
            while (res.next()) System.out.println(res.getString(1) + "\t" + res.getString(2));

            sql = "select * from " + tableName;
            System.out.println("Running :" + sql);
            res = stmt.executeQuery(sql);
            while (res.next()) System.out.println(String.valueOf(res.getInt(1)) + "\t" + res.getString(2));

            sql = "select count(*) from " + tableName;
            res = stmt.executeQuery(sql);
            System.out.println("Running :" + sql);
            while (res.next()) System.out.println(res.getString(1));

        } catch (Exception e) {
            e.printStackTrace();
            System.exit(1);
        } finally {
            if (res != null) res.close();
            if (stmt != null) stmt.close();
            if (con != null) con.close();
        }

    }
}
