• 熟悉常用的HBase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)

    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'
