TSMC 餐廳

  1. 事先準備
    1. 假設：
    2. 1. 建立商店資料
    3. 2 計算單月每個品項的購買次數
    4. 3. 計算當天營業額
    5. 4. 建立索引資料表
    6. 4.b 產生最終報表

事先準備

  • 請先準備以下檔案
    • /tmp/tsmc/store.txt 
      T01;GunLong;  01;20;40;30;50
T02;Esing;  02;50
T03;SunDon; 03;40;30
T04;StarBucks;  04;50;50;20
  • 請準備以下檔案，並將 income 資料夾上傳到hdfs
    • /tmp/tsmc/income/0202.txt 
      waue:T01:P1:xxxxx

可用 tsmcHBase_100204.jar 作此範例測試

假設：

目前有四間商店進駐TSMC餐廳，分別為

位在 第1區的GunLong，品項4項單價為<20,40,30,50>

第2區的ESing,品項1項單價為<50>

第3區的SunDon,品項2項單價為<40,30>

第4區的StarBucks,品項3項單價為<50,50,20>
