  • 熟悉常用的HBase操作

    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:

    • 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;
    • alter 'Student','NAME'=>'course'
    • 向课程列族添加数学列并登记成绩为85;
    • put 'Student','s003','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'
