Edo Interactive在几年前遇到一个大问题：公司使用交易数据来帮助零售商和餐馆进行个性化促销，但其数据仓库没有足够时间去处理所有的信用卡和借记卡交易数据
“我们要花费27小时来处理每日的数据量，”Edo主管基础设施和信息系统的高级副总裁Tim Garnto说道：“所以在2013年，我们放弃了现有的基于PostgreSQL的关系型数据库系统，使用了Hadoop集群作为公司的数
例如我们把scott.dept表生成文本文件的语句写成dept.sql,内容如下:
set pages 50000;
set lines 200;
set trims on;
set heading off;
spool /oracle_backup/log/test/dept.lst;
select deptno||','||dname||','||loc

今天在测试环境使用yum安装，遇到一个问题：
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
处理很简单，修改文件“/etc/yum.repos.d/epel.repo”， 将baseurl的注释取消， mirrorlist注释掉。即可。

今天在linux下做hbase集群的时候，发现hmaster启动成功了，但是用hbase命令进入shell的时候报了一个错误 PleaseHoldException: Master is initializing，查看了日志，大致意思是说master和slave时间不同步，没办法，只好找一种手动同步一下，后来发现一共部署了10来台机器，手动同步偏差又比较大，所以还是从网上找现成的解决方
