Mapping HBase table in Phoenix

Hi Everyone,



When I map a table in Phoenix from Hbase which has two column families, I
could not able to see the data for 2nd column family from Phoenix.



Hbase:



create 'tab_2_cf', 'cf1', 'cf2'



put 'tab_2_cf', 'r1', 'cf1:name', 'asdf'



put 'tab_2_cf', 'r1', 'cf1:address', 'CALIF'



>From Phoenix:



create view "tab_2_cf"(pk varchar primary key, "cf1"."name" varchar,
"cf2"."address" varchar);



queried the table from phoenix, data is being shown as NULL for Column
address.



0: jdbc:phoenix:172.31.45.176:2181:/hbase> select * from "tab_2_cf";

+------------+------------+------------+

|     PK     |    name    |  *address*   |

+------------+------------+------------+

| r1         | asdf       | null       |

+------------+------------+------------+



Any help on this?



Thanks,

Siva.

just as  you said,it has 2 families in your table:'cf1'and 'cf2', ‍
but you mapped "cf2"."address"  into the ‍view and you put "‍address" in 'cf1' family,so you will get a NULL in the view.‍

主题: Mapping HBase table in Phoenix




Hi Everyone,
 
 
 
When I map a table in Phoenix from Hbase which has two column families, I could not able to see the data for 2nd column family from Phoenix.
 
 
 
Hbase:
 
 
 
create 'tab_2_cf', 'cf1', 'cf2'
 
 
 
put 'tab_2_cf', 'r1', 'cf1:name', 'asdf'
 
 
 
put 'tab_2_cf', 'r1', 'cf1:address', 'CALIF'
 
 
 
From Phoenix:
 
 
 
create view "tab_2_cf"(pk varchar primary key, "cf1"."name" varchar, "cf2"."address" varchar);
 
 
 
queried the table from phoenix, data is being shown as NULL for Column address.
 
 
 
0: jdbc:phoenix:172.31.45.176:2181:/hbase> select * from "tab_2_cf";

+------------+------------+------------+
 
 
 
Any help on this?
