Subject RE: Phoenix Array Type Null Element

Hi Kathir

Ideally nulls should work with all the ARRAY types.  Do you find any issues in the behavior
of these ARRAY data types when you use ‘nulls’?

Regards
Ram

What are the other Array base data types (like VARCHAR), that could take null values?

Do the below data types allow NULL as well?

BIGINT ARRAY, DOUBLE ARRAY, DATE ARRAY, VARBINARY ARRAY

Thanks,
Kathir

Ideally varchar array should support NULL. This seems to be a bug.  Can you file a JIRA for
this?
I can come up with a patch ASAP.

Subject: Phoenix Array Type Null Element

Hi,

Is it possible to insert null elements in an array type column?

CREATE TABLE ARRAYTEST124 (ID VARCHAR, NAME VARCHAR ARRAY CONSTRAINT PK PRIMARY KEY(ID))

UPSERT INTO ARRAYTEST124 (ID, NAME) VALUES('123',ARRAY['ABC','XYZ',null])
UPSERT INTO ARRAYTEST124 (ID, NAME) VALUES('123',ARRAY['ABC',null,'XYZ'])
UPSERT INTO ARRAYTEST124 (ID, NAME) VALUES('123',ARRAY[null,'ABC','XYZ'])

I'm using phoenix 4.4.0-HBase-0.98-rc0

I'm getting a null pointer exception, while trying to do the above upserts
