執行環境

  • 檢查是否有加裝 transactional 函式庫
    • 加裝 tableindexed 函式庫
      cp /opt/hbase/contrib/transactional/hbase-*-transactional.jar /opt/hbase/lib/
      
    • 重新啟動 hbase
      /opt/hbase/bin/stop-hbase.sh
      /opt/hbase/bin/start-hbase.sh
      

事先準備

  • 請先準備以下檔案
    • /tmp/itri/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/itri/income/0202.txt
      waue:T01:P1:xxxxx
      jazz:T01:P2:xxxxx
      lia:T01:P3:xxxxx
      hung:T02:P1:xxxxx
      lia:T04:P1:xxxxx
      lia:T04:P1:xxxxx
      hung:T04:P3:xxxxx
      hung:T04:P2:xxxxx
      
    • /tmp/itri/income/0203.txt
      xxx:T01:P4:xxxxx
      ooo:T02:P1:xxxxx
      oo:T03:P1:xxxxx
      xxx:T03:P1:xxxxx
      aaa:T03:P1:xxxxx
      
    • 上傳到 HDFS
      $ /opt/hadoop/bin/hadoop fs -put /tmp/itri/income/ income
      

假設:

目前有四間商店進駐 ITRI ,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>

1. 建立商店資料
