远程启动元数据服务：

nohup bin/hive --servicemetastore&

启动hiveserver2服务

nohup bin/hive --servicehiveserver2 & 以后台进程的方式启动

Java客户端访问

示例代码：

package com.sitech;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

import org.apache.log4j.Logger;

public class T1 {

private static Logger log = Logger.getLogger(T1.class);

private static String driverName =

"org.apache.hive.jdbc.HiveDriver";

public boolean run() {

try {

Class.forName(driverName);

Connection con = null;

con = DriverManager.getConnection(

"jdbc:hive2://172.21.3.170:10000/hivedb",

"", "");

Statement stmt = con.createStatement();

ResultSet res = null;

String sql = "selectcount(*) from test";

System.out.println("Running:" + sql);

res = stmt.executeQuery(sql);

System.out.println("ok");

while (res.next()) {

System.out.println(res.getString(1));

}

return true;

} catch (Exception e) {

e.printStackTrace();

log.error("Connection:" + e.getMessage());

System.out.println("error");

return false;

}

}

public static void main(String[] args)

throws SQLException {

HiveJdbcClienthiveJdbcClient =

new HiveJdbcClient();

hiveJdbcClient.run();

}

}
