You can use the function regexp_replace or regex_extract to get only the product id. Try this:

SELECT  * FROM (select user_id, prod_and_ts.product_id as product_id,
regex_replace(prod_and_ts.timestamps, "#\\d*", "")  as timestamps FROM table2 LATERAL VIEW
explode(purchased_item) exploded_table as prod_and_ts) prod_and_ts;
