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
