Hive Explode / Lateral View multiple arrays

Question

I have a hive table with the following schema:

COOKIE  | PRODUCT_ID | CAT_ID |    QTY    
1234123   [1,2,3]    [r,t,null]  [2,1,null]

How can I normalize the arrays so I get the following result

COOKIE  | PRODUCT_ID | CAT_ID |    QTY

1234123   [1]          [r]         [2]

1234123   [2]          [t]         [1] 

1234123   [3]          null       null 

I have tried the following:

select concat_ws('|',visid_high,visid_low) as cookie
,pid
,catid 
,qty
from table
lateral view explode(productid) ptable as pid
lateral view explode(catalogId) ptable2 as catid 
lateral view explode(qty) ptable3 as qty

however the result comes out as a Cartesian product.

Answer 1

I found a very good solution to this problem without using any UDF, posexplode is a very good solution :

SELECT COOKIE ,
ePRODUCT_ID,
eCAT_ID,
eQTY
FROM TABLE 
LATERAL VIEW posexplode(PRODUCT_ID) ePRODUCT_IDAS seqp, ePRODUCT_ID
LATERAL VIEW posexplode(CAT_ID) eCAT_ID AS seqc, eCAT_ID
LATERAL VIEW posexplode(QTY) eQTY AS seqq, eDateReported
WHERE seqp = seqc AND seqc = seqq;
