熟悉HBase基本操作

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）

put 'Student','188','S_No','2015001'

put 'Student','190','S_No','2015003'

put 'Student','200','S_No','2015003'

put 'Student','188','S_Name','Zhangsan'

put 'Student','190','S_Name','Mary'

put 'Student','200','S_Name','Lisi'

put 'Student','188','S_Sex','male'

put 'Student','190','S_Sex','female'

put 'Student','200','S_Sex','male'

put 'Student','188','S_Age','23'

put 'Student','190','S_Age,'22'

put 'Student','200','S_Age','24'

 

 

 

 

 

 

2.用Hadoop提供的HBase Shell命令完成相同任务：

(1)列出HBase所有的表的相关信息；list

(2)在终端打印出学生表的所有记录数据；

(3)向学生表添加课程列族；

alter 'Student','NAME'=>'course'

(4)向课程列族添加数学列并登记成绩为85；

put 'Student','s003','course:Math','85'

(5)删除课程列；

disable 'Student'

dorp 'Student','course'

(6)统计表的行数；count 's1'

count 'Student'

 

(7)清空指定的表的所有记录数据；truncate 's1'

truncate 'Student'

 

 

向学生表添加课程列族；
