创建表

常用语法：create  '[namespacename:]tablename' [ ,'columnfamilyname1' [  ,'columnfamilyname2, ....]]

hbase(main):002:0> put'test','row2','fam1:a','value'
0 row(s) in 0.3760 seconds
hbase(main):003:0> put 'test','row1','fam1:a','value'
0 row(s) in 0.3760 seconds
hbase(main):004:0> put 'test','row1','fam2:a','value'

 row1                                     column=fam1:a, timestamp=1504767451331, value=value                                                                     
 row1                                     column=fam2:a, timestamp=1504767471977, value=value                                                                     
 row2                                     column=fam1:a, timestamp=1504767600686, value=value                                                                     
 row2                                     column=fam2:a, timestamp=1504767715014, value=value                                                                     
2 row(s) in 0.1120 seconds

 

查看指定列的数据：

hbase(main):004:0> scan 'test',{COLUMNS=> 'fam1:a'}
ROW                                       COLUMN+CELL                                                                                                              
 row1                                     column=fam1:a, timestamp=1504767451331, value=value                                                                     
 row2                                      column=fam1:a,timestamp=1504767600686, value=value

hbase(main):021:0> get 'test','row1'
COLUMN                                     CELL

 fam2:a                                   timestamp=1504767471977, value=value                                                                                    
2 row(s) in 0.1110 seconds

 

使用get查询数据：

语法：get  '[namespacename:]tablename' , 'rowkey' [, 'columnfamliyname[:column]']

详细语法使用help 'get'查看

hbase(main):024:0> get'test','row1','fam1'
COLUMN                                     CELL                                                                                                                    
 fam1:a                                   timestamp=1504768075731, value=\x00\x00\x00\x00\x00\x00\x00\x02

hbase(main):026:0> get 'test','row1','fam1:a'
COLUMN                                     CELL                                                                                                                    
 fam1:a                                   timestamp=1504768075731, value=\x00\x00\x00\x00\x00\x00\x00\x02                                                         
1 row(s) in 0.0430 seconds

 

使用delete删除数据

常用语法：delete '[namespacename:]tablename' , 'rowkey' , 'columnfamliyname:column'

当表中存在只制定了columnfamily没有具体制定column的数据时，delete可以这么用

delete '[namespacename:]tablename' , 'rowkey' , 'columnfamliyname',不存在这样的数据，使用这样的语句不会删除数据。

更详细的语法使用help 'delete'查看

hbase(main):008:0> delete'test','row1','fam1:a'
0 row(s) in 0.3370 seconds
 
hbase(main):009:0> scan 'test'

2 row(s) in 0.0850 seconds

 

使用incr增加数据（默认使用counter实现递增）

常用语法：incr '[namespacename:]tablename' , 'rowkey' , 'columnfamilyname:column'

更详细的语法使用help 'incr'查看

hbase(main):012:0> incr'test','row1','fam1:a'
COUNTER VALUE = 1
0 row(s) in 1.1700 seconds
 
hbase(main):013:0> scan 'test'

hbase(main):014:0> incr'test','row1','fam1:a'
COUNTER VALUE = 2
0 row(s) in 0.0480 seconds
 
hbase(main):015:0> scan 'test'
ROW                                       COLUMN+CELL                                                                                                             
 row1                                     column=fam1:a, timestamp=1504768075731,value=\x00\x00\x00\x00\x00\x00\x00\x02

ROW                                        COLUMN+CELL                                                                                                             
 row1                                     column=fam1:a, timestamp=1504768075731,value=\x00\x00\x00\x00\x00\x00\x00\x02
