Alex的Hadoop菜鸟教程:第8课Sqoop1导入Hbase以及Hive

CREATE TABLE `employee` ( 
 `id` int(11) NOT NULL, 
 `name` varchar(20) NOT NULL, 
 PRIMARY KEY (`id`) 
) ENGINE=MyISAM DEFAULT CHARSET=utf8; 

insert into employee (id,name) values (1,'michael'); 
insert into employee (id,name) values (2,'ted'); 
insert into employee (id,name) values (3,'jack'); 

hbase(main):006:0> create 'employee','info'
0 row(s) in 0.4440 seconds

=> Hbase::Table - employee
