1、创建test，如果存在先删除

hbase(main):010:0> disable ‘test‘
0 row(s) in 1.4250 seconds

hbase(main):011:0> drop ‘test‘
0 row(s) in 0.5540 seconds

hbase(main):012:0> create ‘test‘,‘grade‘, ‘course‘
0 row(s) in 0.7450 seconds

=> Hbase::Table - test

2、查看数据表

hbase(main):013:0> list
TABLE                                                                                                                             
test                                                                                                                              
2 row(s) in 0.0200 seconds

3、查看数据表结构

hbase(main):015:0> describe ‘test‘
DESCRIPTION                                                                          ENABLED                                      
 ‘test‘, {NAME => ‘course‘, DATA_BLOCK_ENCODING => ‘NONE‘, BLOOMFILTER => ‘ROW‘, REP true                                         
 LICATION_SCOPE => ‘0‘, VERSIONS => ‘1‘, COMPRESSION => ‘NONE‘, MIN_VERSIONS => ‘0‘,                                              
  TTL => ‘FOREVER‘, KEEP_DELETED_CELLS => ‘false‘, BLOCKSIZE => ‘65536‘, IN_MEMORY =                                              
 > ‘false‘, BLOCKCACHE => ‘true‘}, {NAME => ‘grade‘, DATA_BLOCK_ENCODING => ‘NONE‘,                                               
 BLOOMFILTER => ‘ROW‘, REPLICATION_SCOPE => ‘0‘, VERSIONS => ‘1‘, COMPRESSION => ‘NO                                              
 NE‘, MIN_VERSIONS => ‘0‘, TTL => ‘FOREVER‘, KEEP_DELETED_CELLS => ‘false‘, BLOCKSIZ                                              
 E => ‘65536‘, IN_MEMORY => ‘false‘, BLOCKCACHE => ‘true‘}                                                                        
1 row(s) in 0.0630 seconds

4、插入数据

(1) 加入一行数据,行名称为zkb 列族grad的列名为”” 值位5
hbase(main):006:0> put ‘test‘,‘zkb‘,‘grade:‘,‘5‘      
0 row(s) in 0.0420 seconds
(2) 给zkb这一行的数据的列族course添加一列<math,97>
hbase(main):007:0> put ‘test‘,‘zkb‘,‘course:math‘,‘97‘
0 row(s) in 0.0270 seconds
(3) 给zkb这一行的数据的列族course添加一列<art,87>
hbase(main):008:0> put ‘test‘,‘zkb‘,‘course:art‘,‘87‘
0 row(s) in 0.0260 seconds
(4) 加入一行数据,行名称为baoniu 列族grad的列名为”” 值为4
hbase(main):009:0> put ‘test‘,‘baoniu‘,‘grade:‘,‘4‘   
0 row(s) in 0.0260 seconds
(5) 给baoniu这一行的数据的列族course添加一列<math,89>
hbase(main):010:0> put ‘test‘,‘baoniu‘,‘course:math‘,‘89‘
0 row(s) in 0.0270 seconds
(6) 给Jerry这一行的数据的列族course添加一列<art,80>
hbase(main):011:0> put ‘test‘,‘baoniu‘,‘course:art‘,‘80‘
0 row(s) in 0.0270 seconds

5、查看一条数据

hbase(main):028:0> get ‘test‘,‘zkb‘
COLUMN                            CELL                                                                                            
 course:art                       timestamp=1417327162462, value=87                                                               
 course:math                      timestamp=1417327154780, value=97                                                               
 grade:                           timestamp=1417326981345, value=5                                                                
3 row(s) in 0.0200 seconds

6、查看所有数据

hbase(main):029:0> scan ‘test‘
ROW                               COLUMN+CELL                                                                                     
 baoniu                           column=course:art, timestamp=1417327239480, value=80                                            
 baoniu                           column=course:math, timestamp=1417327233828, value=89                                           
 baoniu                           column=grade:, timestamp=1417327206239, value=4                                                 
 zkb                              column=course:art, timestamp=1417327162462, value=87                                            
 zkb                              column=course:math, timestamp=1417327154780, value=97                                           
 zkb                              column=grade:, timestamp=1417326981345, value=5                                                 
2 row(s) in 0.0130 seconds

7、指定搜索条件的查询，startrow和stoprow，一般程序开发都使用它

hbase(main):030:0> scan ‘test‘,{STARTROW=>‘baoniu‘, STOPROW=>‘zkb‘}
ROW                               COLUMN+CELL                                                                                     
 baoniu                           column=course:art, timestamp=1417327239480, value=80                                            
 baoniu                           column=course:math, timestamp=1417327233828, value=89                                           
 baoniu                           column=grade:, timestamp=1417327206239, value=4                                                 
1 row(s) in 0.0230 seconds

8、查看指定列的数据

hbase(main):037:0> scan ‘test‘,{STARTROW=>‘baoniu‘, STOPROW=>‘zkb‘, COLUMNS=>‘course‘}
ROW                               COLUMN+CELL                                                                                     
 baoniu                           column=course:art, timestamp=1417327239480, value=80                                            
 baoniu                           column=course:math, timestamp=1417327233828, value=89                                           
1 row(s) in 0.0160 seconds

9、添加filter 

命令行： scan ‘nd_shop_rpt_new_d‘,{STARTROW=>‘2014-11-05‘, STOPROW=>‘2014-11-29‘, FILTER => "( SingleColumnValueFilter(‘t‘, ‘shop_id‘, =, ‘binary:100705598‘) AND SingleColumnValueFilter(‘t‘, ‘auction_id‘, =, ‘binary:42516637646‘))"}

 

hbase(main):012:0> scan ‘nd_shop_rpt_new_d‘,{STARTROW=>‘2014-11-05‘, STOPROW=>‘2014-11-29‘, FILTER => "( SingleColumnValueFilter(‘t‘, ‘shop_id‘, =, ‘binary:100705598‘) AND SingleColumnValueFilter(‘t‘, ‘auction_id‘, =, ‘binary:42516637646‘))"}
ROW                               COLUMN+CELL                                                                                     
2014-11-22_100705598_42516637646 column=t:auction_new_time, timestamp=1417348934182, value=                                      
 2014-11-22_100705598_42516637646 column=t:auction_shelf_time, timestamp=1417348934182, value=2014-11-21 14:00:05                 
 2014-11-22_100705598_42516637646 column=t:cat_id, timestamp=1417348934182, value=121452038                                       
 2014-11-22_100705598_42516637646 column=t:cat_name, timestamp=1417348934182, value=                                              
 2014-11-22_100705598_42516637646 column=t:seller_id, timestamp=1417348934182, value=-99                                          
 2014-11-22_100705598_42516637646 column=t:shop_id, timestamp=1417348934182, value=100705598                                      
 2014-11-22_100705598_42516637646 column=t:thedate, timestamp=1417348934182, value=2014-11-22                                     
 2014-11-22_100705598_42516637646 column=t:trade_amount, timestamp=1417348934182, value=1                                         
 2014-11-22_100705598_42516637646 column=t:trade_amt, timestamp=1417348934182, value=68.0                                         
2 row(s) in 1.4770 second
