KYLIN 例行调度 自动BULID

KYLIN提供RESTFUL 接口，通过请求&crontab 可实现例行调度

参考url:

http://kylin.apache.org/docs15/howto/howto_use_restapi.html#get-job-status

实现步骤：

1、shell脚本加入下面代码实现BULID请求

java -jar KylinInterface.jar CUBE_NAME 20160806 20160807 BUILD

2、crontab 设置自动执行

以下为jar对应代码

package kylin;



import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.text.ParseException;
import java.text.SimpleDateFormat;

import org.apache.commons.codec.binary.Base64;
