大家知道，直接從hbase的讀取資料是一個比較繁鎖的過程，需要java程式碼或是spark 查詢
通過Hive整合HBase,可以通過hive表查詢hbase資料，下面是測試過程
--建立hbase表

create "user","account","address","info","userid"

--建立對映hbase表列族的hive外部表

CREATE EXTERNAL TABLE hbase_user(key string, idcard string,passport string,country string,name string,password string,
   province string,city string,age string,sex string ,id string)   
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'  
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,account:idcard,account:passport,account:country,account:name,account:password,
   address:province,address:city,info:age,info:sex,userid:id")   
TBLPROPERTIES("hbase.table.name" = "user");
 

--新增hbase新的記錄

put 'user','zhangsan','account:idcard','420923156366998855'
put 'user','lisi','account:idcard','520369856366998855'
put 'user','lisi','account:country','china'
put 'user','lichangzai','account:idcard','132901981090831721'
put 'user','changfei','account:idcard','132901983090831736'
put 'user','lichangzai','info:age','35'
put 'user','lichangzai','info:sex','man'
put 'user','changfei','info:age','30'
 

-- hive查詢hbase資料

hive> select * from user;

--修改hbase記錄，直接put行建的的列值

put 'user','lisi','account:idcard','520369856366998856'

--新增列族

alter 'user','work','adu'

--新增新列族的欄位值

put 'user','lichangzai','edu:mschool','rq no.1'
put 'user','lichangzai','edu:university','qhddx'
put 'user','lichangzai','work:company1','12580'
put 'user','lichangzai','work:company2','china mobile'
put 'user','lichangzai','info:site','blog.csdn.net/lichangzai'
put 'user','lichangzai','info:mobile','13712345678'
put 'user','changfei','edu:university','bjdx'
put 'user','changfei','work:company1','LG'
put 'user','changfei','info:mobile','13598765401'
put 'user','changfei','info:site','hi.baidu/lichangzai'
 

再查詢hive表，可以看到新新增的欄位值沒有被顯示。

下面可以建立刪除hive外部表，再重新建立對映hbase的外部表，把hbase新增的列族對映進來
--刪除hive外部表（外部表的特性，表會刪除，資料還在）
hive> drop table user;

--重新建立外表
CREATE EXTERNAL TABLE hbase_user(key string, idcard string,passport string,country string,name string,password string,
   province string,city string,age string,sex string,site string,mobile string,work1 string,work2 string,edu_mschool string,edu_univ string,id string)   
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'  
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,account:idcard,account:passport,account:country,account:name,account:password,
   address:province,address:city,info:age,info:sex,info:site,info:mobile,work:company1,work:company2,edu:mschool,edu:university,userid:id")   
TBLPROPERTIES("hbase.table.name" = "user");

--再次查詢hive表
select * from hbase_user
