一个student表，表的逻辑模型如下： 行键为学号，时间戳是自动添加的，列族name是名字，列族score是各科分数。行键是唯一的。
| 行键 | 时间戳 | 列族name | 列族score |
| 20130001 | T2 | 'zhangsan' | |
| T3 | score:Chinese='90' | ||
| T4 | score:English='80' | ||
| 20130002 | T5 | 'lisi' | |
| T6 | score:Chinese='95' | ||
| ...... | Tn |
进入HBase的shell：
[coder@h1 hbase-0.90.5]$ bin/hbase shell HBase Shell; enter 'help<RETURN>' for list of supported commands. Type "exit<RETURN>" to leave the HBase Shell Version 0.90.5, r1212209, Fri Dec 9 05:40:36 UTC 2011 hbase(main):001:0>
1、创建student表
hbase(main):002:0> create 'student','name','score' 0 row(s) in 2.0570 seconds hbase(main):003:0>
student：表名
name：列族
score：列族
2、查看已创建的表
hbase(main):001:0> list TABLE student 1 row(s) in 0.7590 seconds hbase(main):002:0>
3、向表中插入数据
使用put命令插入数据，参数为表名、行名（行键）、列名、值，其中列名需要列族作为前缀。
1）向student表中插入学号（行键）为2013001、名字为zhangsan的记录
hbase(main):001:0> put 'student','2013001','name:','zhangsan' 0 row(s) in 1.1090 seconds
2）查看表的记录
hbase(main):002:0> scan 'student' ROW COLUMN+CELL 2013001 column=name:, timestamp=1365846723665, value=zhangsan 1 row(s) in 0.2110 seconds
3）给学号为2013001的学生记录分数
hbase(main):003:0> put 'student','2013001','score:Chinese','90' 0 row(s) in 0.0360 seconds
hbase(main):005:0> put 'student','2013001','score:English','80' 0 row(s) in 0.0290 seconds
hbase(main):006:0> scan 'student' ROW COLUMN+CELL 2013001 column=name:, timestamp=1365846723665, value=zhangsan 2013001 column=score:Chinese, timestamp=1365846877328, value=90 2013001 column=score:English, timestamp=1365846957089, value=80 1 row(s) in 0.0580 seconds
4）查看表中记录总数
hbase(main):007:0> count 'student' 1 row(s) in 0.0990 seconds
4、查看一行记录
使用get命令，参数为表名、行键
hbase(main):007:0> get 'student','2013001' COLUMN CELL name: timestamp=1365846723665, value=zhangsan score:Chinese timestamp=1365846877328, value=90 score:English timestamp=1365846957089, value=80 3 row(s) in 0.0350 seconds
5、判读一个表是否存在
hbase(main):001:0> exists 'student' Table student does exist 0 row(s) in 1.0400 seconds hbase(main):002:0> exists 'student2' Table student2 does not exist 0 row(s) in 0.0150 seconds
6、更新一条记录
hbase(main):001:0> put 'student','2013001','score:Chinese','100' 0 row(s) in 0.8070 seconds hbase(main):002:0> get 'student','2013001' COLUMN CELL name: timestamp=1365846723665, value=zhangsan score:Chinese timestamp=1365848492778, value=100 score:English timestamp=1365846957089, value=80 3 row(s) in 0.0690 seconds hbase(main):003:0>
7、获取某一列的值
hbase(main):002:0> get 'student','2013001','score' COLUMN CELL score:Chinese timestamp=1365848492778, value=100 score:English timestamp=1365846957089, value=80 2 row(s) in 0.0340 seconds hbase(main):003:0> get 'student','2013001','score:Chinese' COLUMN CELL score:Chinese timestamp=1365848492778, value=100 1 row(s) in 0.0320 seconds hbase(main):004:0>
8、删除整行
把行键为2013002的这一条记录删掉
hbase(main):001:0> scan 'student' ROW COLUMN+CELL 2013001 column=name:, timestamp=1365846723665, value=zhangsan 2013001 column=score:Chinese, timestamp=1365848492778, value=100 2013001 column=score:English, timestamp=1365846957089, value=80 2013002 column=name:, timestamp=1365847639588, value=lisi 2013002 column=score:Chinese, timestamp=1365847666351, value=70 2013002 column=score:English, timestamp=1365847709403, value=85 2 row(s) in 0.7380 seconds hbase(main):002:0> deleteall 'student','2013002' 0 row(s) in 0.0150 seconds hbase(main):003:0> scan 'student' ROW COLUMN+CELL 2013001 column=name:, timestamp=1365846723665, value=zhangsan 2013001 column=score:Chinese, timestamp=1365848492778, value=100 2013001 column=score:English, timestamp=1365846957089, value=80 1 row(s) in 0.0390 seconds hbase(main):004:0>
9、删除表
删除表之前需要先disable表
hbase(main):005:0> disable 'user' 0 row(s) in 2.1600 seconds hbase(main):006:0> drop 'user' 0 row(s) in 1.3750 seconds
