ERROR: java.lang.Long cannot be cast to java.lang.String

[sonia gehlot]

Hi,

I have pigscript in which I am flattening it and assign schema to it and
trying to do some REGEX matching on top of it after that converting it to
INT. But its giving me error "ERROR: java.lang.Long cannot be cast to java.
lang.String"

Here is a snippet of code where I am getting error:
--------------------------------

final_flatten = foreach flattened_further generate .. watched_evidence,
flatten(myop) as (rank:int,list:chararray), row..device_type_id;


final_cast = foreach final_flatten generate

(int)dateint,

(long)event_utc_ms,

(int)hour,

(long)(RegexMatch((chararray) account_id, '\\d+') == 1 ? (chararray)account_id
: '-1001') as account_id,

request_data_type,

client_request_id,

(int)(RegexMatch((chararray) device_type_id, '\\d+') == 1 ?
(chararray)device_type_id
: '-1001') as device_type_id,

(int)(RegexMatch((chararray) max_list_index, '\\d+') == 1 ?
(chararray)max_list_index
: '-1001') as max_list_index,

esn,

(long)(RegexMatch((chararray) epoch_create_ts, '\\d+') == 1 ?
(chararray)epoch_create_ts
: '-1001') as request_create_ts,

socially_connected,

gps_model,

country_iso_code,

status_code,

uuid,

(long)(RegexMatch((chararray) visitorid, '\\d+') == 1 ?
(chararray)visitorid: '-1001') as account_profile_id,

(int)(RegexMatch((chararray) track_id, '\\d+') == 1 ? (chararray)track_id :
'-1001') as location_id,

sub_root_uuid,

list_type,

item_type,

hasevidence,

listContext,

(int)(RegexMatch((chararray) genre_id, '\\d+') == 1 ? (chararray)genre_id :
'-1001') as genre_id,

taste_evidence,

rated_evidence,

watched_evidence,

*(int)(RegexMatch((chararray) list, '\\d+') == 1 ? (chararray)list :
'-1001') as source_title_id,*

row as presentation_row_number,

rank as presentation_rank_number;

z = limit final_cast 10;

dump z;

------------------------------------

It is returning correct results other than one field

"*(int)(RegexMatch((chararray) list, '\\d+') == 1 ? (chararray)list :
'-1001') as source_title_id,*"

for this I am getting error *"ERROR: java.lang.Long cannot be cast to java.
lang.String"*

I tried explicit casting, but it is still giving me error.

Any idea what I am doing wrong here.

Thanks,

Sonia
