- 首先给出本次操作的数据
create 'student','info','address'
put 'student','1','info:age','20'
put 'student','1','info:name','wang'
put 'student','1','info:class','1'
put 'student','1','address:city','zhengzhou'
put 'student','1','address:area','High-tech zone'
put 'student','2','info:age','21'
put 'student','2','info:name','yang'
put 'student','2','info:class','1'
put 'student','2','address:city','beijing'
put 'student','2','address:area','CBD'
put 'student','3','info:age','22'
put 'student','3','info:name','zhao'
put 'student','3','info:class','2'
put 'student','3','address:city','shanghai'
put 'student','3','address:area','pudong'
scan 'student'
2.首先执行,创建表,增加数据操作,执行脚本 /bin/hbase shell ./student.txt,然后查看内容 scan ‘student’
hbase(main):001:0> scan 'student'
ROW COLUMN+CELL
1 column=address:area, timestamp=1491533426260, value=High-tech zone
1 column=address:city, timestamp=1491533426239, value=zhengzhou
1 column=info:age, timestamp=1491533426179, value=20
1 column=info:class, timestamp=1491533426218, value=1
1 column=info:name, timestamp=1491533426211, value=wang
2 column=address:area, timestamp=1491533426297, value=CBD
2 column=address:city, timestamp=1491533426292, value=beijing
2 column=info:age, timestamp=1491533426269, value=21
2 column=info:class, timestamp=1491533426287, value=1
2 column=info:name, timestamp=1491533426277, value=yang
3 column=address:area, timestamp=1491533426329, value=pudong
3 column=address:city, timestamp=1491533426323, value=shanghai
3 column=info:age, timestamp=1491533426305, value=22
3 column=info:class, timestamp=1491533426317, value=2
3 column=info:name, timestamp=1491533426311, value=zhao
3 row(s) in 0.1940 seconds
3.修改操作 也是用put命令,就是重新添加内容把,把以前的内容覆盖。
格式 put 't1', 'r1', 'c1', 'value'
命令 put 'student','1','info:age','18'
结果
hbase(main):010:0> get 'student','1'
COLUMN CELL
address:area timestamp=1491533426260, value=High-tech zone
address:city timestamp=1491533426239, value=zhengzhou
info:age timestamp=1491533823331, value=18
info:class timestamp=1491533426218, value=1
info:name timestamp=1491533426211, value=wang
5 row(s) in 0.0110 seconds
4.删除操作,分为删除单元格的内容,和整行删除
单元格
hbase(main):012:0> delete 'student','1','info:name'
0 row(s) in 0.0800 seconds
hbase(main):014:0> get 'student','1'
COLUMN CELL
address:area timestamp=1491533426260, value=High-tech zone
address:city timestamp=1491533426239, value=zhengzhou
info:age timestamp=1491533823331, value=18
info:class timestamp=1491533426218, value=1
4 row(s) in 0.0120 seconds
整行
hbase(main):023:0> deleteall 'student','1'
0 row(s) in 0.0260 seconds
hbase(main):024:0> get 'student','1'
COLUMN CELL
0 row(s) in 0.0070 seconds
5.查询
单行查询
hbase(main):026:0> get 'student','2'
COLUMN CELL
address:area timestamp=1491533426297, value=CBD
address:city timestamp=1491533426292, value=beijing
info:age timestamp=1491533426269, value=21
info:class timestamp=1491533426287, value=1
info:name timestamp=1491533426277, value=yang
5 row(s) in 0.0190 seconds
指定列族
hbase(main):028:0> get 'student', '2', {COLUMN => 'info'}
COLUMN CELL
info:age timestamp=1491533426269, value=21
info:class timestamp=1491533426287, value=1
info:name timestamp=1491533426277, value=yang
3 row(s) in 0.0150 seconds
指定列名
hbase(main):029:0> get 'student', '2', {COLUMN => 'info:age'}
COLUMN CELL
info:age timestamp=1491533426269, value=21
1 row(s) in 0.0080 seconds
使用scan,指定startrow
hbase(main):031:0> scan 'student', {COLUMNS => ['info:age', 'address'], LIMIT => 10, STARTROW => '2'}
ROW COLUMN+CELL
2 column=address:area, timestamp=1491533426297, value=CBD
2 column=address:city, timestamp=1491533426292, value=beijing
2 column=info:age, timestamp=1491533426269, value=21
3 column=address:area, timestamp=1491533426329, value=pudong
3 column=address:city, timestamp=1491533426323, value=shanghai
3 column=info:age, timestamp=1491533426305, value=22
2 row(s) in 0.0190 seconds
scan指定过滤
hbase(main):005:0> scan 'student',{FILTER=>"(TimestampsFilter (1491533426297))"}
ROW COLUMN+CELL
2 column=address:area, timestamp=1491533426297, value=CBD
1 row(s) in 0.0170 seconds
