如果想启动Hiveserver,可以在后台启动执行这个Hive服务:

hiveserver2 start &

HiveServer使用Thrift提供服务,Thrift提供了一个接口语言.通过这些接口,Thrift编译器可以产生创建网络RPC的多种语言的客户端的代码.

简单处理例子

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

/**

public class JDBCHive {
    private static String Driver = "org.apache.hive.jdbc.HiveDriver";
    private static String URL= "jdbc:hive2://106.75.9.213:10000/default";
    private static String name ="root";
    private static String password="xxxxx";

    public static void main(String[] args) {
        try{

            Class.forName(Driver);
            Connection  connection  = DriverManager.getConnection(URL,name,password);
            Statement statement = connection.createStatement();
            String sql = "show tables";
            ResultSet  rs  = statement.executeQuery(sql);
            while (rs.next()){
                System.out.println(rs.getString(1));
            }
        }catch (Exception e){
            e.printStackTrace();
        }

    }

}

通过thrift进行通讯，hive支持多语言接口

执行以后可以看到对应的表信息

代表通过thrift和hive通讯成功
