1. 以下关系型数据库中的表和数据,要求将其转换为适合于HBase存储的表并插入数据:

学生表(Student)(不包括最后一列)

学号(S_No)

姓名(S_Name)

性别(S_Sex)

年龄(S_Age)

课程(course)

2015001

Zhangsan

male

23

 

2015003

Mary

female

22

 

2015003

Lisi

male

24

数学(Math)85

熟悉常用的HBase操作-LMLPHP
create 'Student','sname','ssex','sage'

put 'Student','2015001','sname','Zhangsan'

put 'Student','2015001','ssex','male'

put 'Student','2015001','sage','23'

put 'Student','2015002','sname','Mary'

put 'Student','2015002','ssex','female'

put 'Student','2015002','sage','22'

put 'Student','2015003','sname','Lisi'

put 'Student','2015003','ssex','male'

put 'Student','2015003','sage','24

2. 用Hadoop提供的HBase Shell命令完成相同任务:

  • 列出HBase所有的表的相关信息;list

    list
  • 在终端打印出学生表的所有记录数据;
    scan 'student'
  • 向学生表添加课程列族;
    alter ‘student',NAME=>'course'
  • 向课程列族添加数学列并登记成绩为85;
    put 'student','3','course:Math','85'
  • 删除课程列;
    dorp 'student','course'
  • 统计表的行数;count 's1'
    count 'student'
  • 清空指定的表的所有记录数据:truncate 's1'
    truncate 'student'
