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)

create Student,  S_No  ,S_Name, ’S_Sex’,S_Age
put Student,s001,S_No,2015001
put Student,s001,S_Name,Zhangsan
put Student,s001,S_Sex,male
put Student,s001,S_Age,23
put Student,s002,S_No,2015003
put Student,s002,S_Name,Mary
put Student,s002,S_Sex,female
put Student,s002,S_Age,22
put Student,s003,S_No,2015003
put Student,s003,S_Name,Lisi
put Student,s003,S_Sex,male
put Student,s003,S_Age,24

2. 用Hadoop提供的HBase Shell命令完成相同任务:

list
scan Student
alter Student,NAME=>course
put Student,s003,course:Math,85
dorp Student,course
count s1
count Student
truncate s1
truncate Student
