Hi All,I have some issue with using map data structure. Any help will be great.
Product is too fine-scale so we turn that into classes. I have a file that has
a map stored in the following format:
// Loading the raw data.raw_customer_data = LOAD 'cust_clean.tsv' AS
(cust_id:chararray, session_id:chararray, ordering_date:chararray, prod_id:
chararray);
I want to turn product id to class_id using the below map. Basically given a
customer info with prod_id, I want to turn that into customer info with
class_id.prodid_to_class_id = LOAD 'structured/prod_id_to_class_id_map.txt' as
(prod_to_class_map: map[]);
prod_id_to_class_id_map.txt has the following format:prod_id#class_id
[524145#1204022AC][526457#1202465BC][2133411#1201978CC][6203089#121537AC]
meds_to_gen_c_mapped = FOREACH raw_meds_data GENERATE fake_pat_id, fake_enc_id,
prodid_to_class_id:: prod_to_class_map#'prod_id';
I get error that prodid_to_class_id:: prod_to_class_map does not exist.
Also, prodid_to_class_id:: prod_to_class_map#'prod_id' is this correct way to
deference when I want to use raw_customer_data:: prod_id as the key in the map.
