Hi

   You can override the behavior by setting the property phoenix.schema.dropMetaData to FALSE. For further reading, http://phoenix.incubator.apache.org/language/index.html#drop_table.

Firas, 

I have the follow table in hbase:

hbase(main):032:0> scan 'test'

ROW                      COLUMN+CELL                                                         

 row1                    column=cf:a, timestamp=1397068853016, value=value1                  

 row2                    column=cf:b, timestamp=1397068857098, value=value2                  

 row3                    column=cf:c, timestamp=1397068861755, value=value3

When a try to create table using Phoenix, use the command:

 CREATE table "test" ( pk VARCHAR PRIMARY KEY, "cf".”val” VARCHAR );

The result is :

PK           val

row1        <null>
row2        <null>
row3         <null>

Could you help me?

Thank you.

Hi Firas,

 

                Phoenix doesn’t work with Accumulo.  

                                                                                                              

Kindly check the below link for more details,

Hi all,

 

Does phoenix work only with HBase or does it also work with Accumulo?

 

Thanks,

Firas

Hi Daniel,

 

                You mapped the HBase table using the below statement,

                                        CREATE VIEW "t1" ( pk VARCHAR PRIMARY KEY, "f1".val VARCHAR );

                By default, Phoenix sends characters in capital letter, so here second column of view is mapped to the qualifier “f1:VAL”.

 

But  you inserted records at HBase in “f1:val” instead of “f1:VAL” as,

r1   column=f1:val, timestamp=1396558762590, value=a

 

                So NULL value is displayed in VAL column at Phoenix side.  

 

You can map as "f1".”val” to resolve this or insert records in “f1:VAL”.

 

Cheers,

Pankaj

Hi all,

 

I spent a couple of hours today trying phoenix for the first time, looks amazing.

 

My final objective is to do SQL on a big hbase table that has a composite key, i decided to start slow and I was able to create a table on phoenix, upsert values and see them on hbase, but I am not able to do the oposite: map (using a view) values on an existing hbase to a phoenix table, i am always getting "null" values.

 

Here is a basic example copied from the docs:

 

HBASE:

> create 't1', {NAME => 'f1', VERSIONS => 5} 

 

PHOENIX:

> CREATE VIEW "t1" ( pk VARCHAR PRIMARY KEY, "f1".val VARCHAR );
> select * from "t1";
+------------+------------+
|     PK     |    VAL     |
+------------+------------+
+------------+------------+ 

 

Works fine since there is no data.

 

I add data to hbase:

> put 't1,'r1','f1','a'

> scan 't1'

ROW                                           COLUMN+CELL

 r1                                           column=f1:, timestamp=1396558806334, value=a

 

But if i try to select from phoenix i get only null values.:

> select * from "t1";

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

|     PK     |    VAL     |

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

| r1         | null       |

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

 

I also tried to save it on an specific column in the column family:

 

> scan 't1'

ROW                                           COLUMN+CELL

 r1                                           column=f1:, timestamp=1396558806334, value=a

 r1                                           column=f1:val, timestamp=1396558762590, value=a

 

I also tried to change from varchar to integer and insert numbers but i got the same result in both cases.

 

I am using phoenix 2.2.0 on EMR.

 

Any help you can give me is appreciated.

 

Thanks,

Daniel
