熟悉常用的HBase操作

1.

create 'Student', ' S_No  ','S_Name', ’S_Sex’,'S_Age'
put 'Student','s001','S_No','2015001'
put 'Student','s001','S_Name','lgd'
put 'Student','s001','S_Sex','male'
put 'Student','s001','S_Age','21'
put 'Student','s002','S_No','2015003'
put 'Student','s002','S_Name','lgc'
put 'Student','s002','S_Sex','female'
put 'Student','s002','S_Age','20'
put 'Student','s003','S_No','2015003'
put 'Student','s003','S_Name','lgf'
put 'Student','s003','S_Sex','male'
put 'Student','s003','S_Age','19'

2.

• 列出HBase所有的表的相关信息；list
• 在终端打印出学生表的所有记录数据；
• 向学生表添加课程列族；
• 向课程列族添加数学列并登记成绩为85；
• 删除课程列；
• 统计表的行数；count 's1'
• 清空指定的表的所有记录数据；truncate 's1'

list

scan 'Student'

alter ‘Student',NAME=>'course' 

put 'Student','3','course:Math','85'

dorp 'Student','course'

count 'Student'

truncate 'Student'
