Yes Ram, i get below issues

*BIGINT ARRAY*

CREATE TABLE BIARRAYNULLTEST1 (ID VARCHAR, SALES BIGINT ARRAY CONSTRAINT PK
PRIMARY KEY (ID))

Hbase>UPSERT INTO BIARRAYNULLTEST1 (ID, SALES)
VALUES('123',ARRAY[1,2,null])
org.apache.phoenix.schema.TypeMismatchException: ERROR 203 (22005): Type

Any problem with the syntax above for upsert of bigint array?

*DOUBLE ARRAY*

I'm getting back 0.0 instead of null references from the array when i do a
select

CREATE TABLE DBLARRAYNULLTEST (ID VARCHAR, AMOUNTS DOUBLE ARRAY CONSTRAINT
PK PRIMARY KEY(ID))

UPSERT INTO DBLARRAYNULLTEST(ID,AMOUNTS) VALUES('123',ARRAY[1.0,null,2.0])
SELECT * FROM DBLARRAYNULLTEST
123|[1.0, 0.0, 2.0]

UPSERT INTO DBLARRAYNULLTEST(ID,AMOUNTS) VALUES('123',ARRAY[null,1.0,2.0])
SELECT * FROM DBLARRAYNULLTEST
123|[0.0, 1.0, 2.0]

Also, we are planning to use TIMESTAMP array with possible null values in
it. I'll test that as well and will let you know.

Below are the critical ones for us that should accept null values

VARCHAR ARRAY (*You have fixed this yesterday*)
BIGINT ARRAY
DOUBLE ARRAY
TIMESTAMP ARRAY

Thanks,
Kathir
