1. HBase Shell操作连接集群
hbase shell

2. 创建表
create 'user','base_info'

3. 向表中添加数据
put 'user', 'rowkey_10', 'base_info:username', '张三'
put 'user', 'rowkey_10', 'base_info:birthday', '2014-07-10'
put 'user','rowkey_10','base_info:sex','1'
put 'user','rowkey_10','base_info:address','北京市'

put 'user','rowkey_16','base_info:username','张小明'
put 'user','rowkey_16','base_info:birthday','2014-07-10'
put 'user','rowkey_16','base_info:sex','1'
put 'user','rowkey_16','base_info:address','北京'

put 'user','rowkey_22','base_info:username','陈小明'
put 'user','rowkey_22','base_info:birthday','2014-07-10'
put 'user','rowkey_22','base_info:sex','1'
put 'user','rowkey_22','base_info:address','上海'

put 'user','rowkey_24','base_info:username','张三丰'
put 'user','rowkey_24','base_info:birthday','2014-07-10'
put 'user','rowkey_24','base_info:sex','1'
put 'user','rowkey_24','base_info:address','河南'

put 'user','rowkey_25','base_info:username','陈大明'
put 'user','rowkey_25','base_info:birthday','2014-07-10'
put 'user','rowkey_25','base_info:sex','1'
put 'user','rowkey_25','base_info:address','西安'

4. 查询表中的所有数据
scan 'user'

5. 查询某个rowkey的数据
get 'user', 'rowkey_16'

6. 查询某个列簇的数据
get 'user', 'rowkey_16', 'base_info'
get 'user', 'rowkey_16', 'base_info:username'
get 'user', 'rowkey_16', {COLUMN => ['base_info:username', 'base_info:sex']}

7. 删除表中的数据
delete 'user', 'rowkey_16', 'base_info:username'

8. 清空数据
truncate 'user'

9. 操作列簇
alter 'user'， NAME => 'f2'
alter 'user', 'delete' => 'f2'

10. 删除表
一定要先disable 表，然后才能删除表
