今天继续学习hbase

我简化的向数据库里面这样操作

create 'Stu1','name','score'
put 'Stu1','1001','name','zhangsan'
put 'Stu1','1001','score:English','69'
put 'Stu1','1001','score:Math','86'
put 'Stu1','1001','score:Computer','77'
put 'Stu1','1002','name','lisi'
put 'Stu1','1002','score:English','55'
put 'Stu1','1002','score:Math','100'
put 'Stu1','1002','score:Computer','88'

get 'Stu1','1001','score:Computer'

put 'Stu1','1002','score:Math','95'
get 'Stu1','1002','score:Math'

值得注意的是hbase的更新操作只需继续往里面插入即可

更新指定字段的数据

hbase(main):012:0> put 'student','1001','info:name','Nick'

hbase(main):013:0> put 'student','1001','info:age','100'

查看“指定行”或“指定列族:列”的数据

hbase(main):014:0> get 'student','1001'

hbase(main):015:0> get 'student','1001','info:name'
