hbase shell 查看列名_HBASE 常用shell命令,增删改查方法

1、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
