列出HBase全部的表的相關信息;list
create 'Student','S_No','S_Name','S_Sex','S_Age'
在終端打印出學生表的全部記錄數據;
scan 'Student'
向學生表添加課程列族;
alter 'Student','NAME'=>'course'
向課程列族添加數學列並登記成績爲85;
put 'Student','s003','course:Math','85'
刪除課程列;
dorp 'Student','course'
統計表的行數;count 's1'
count 'Student'
清空指定的表的全部記錄數據;truncate 's1'
truncate 'Student'
