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;
