Pig script shows no data

Hi,

I am running below pig script and it is executing successfully but while going through the result from query history it show – no result found. while when I checked in the file it contains 54 rows.

Product= LOAD ‘Product’ AS (Name,ProductNumber,Color);
Fltrd= FILTER Product BY Color == ‘Black';
Dump Fltrd;

Does anyone has hint what wrong I am doing.

Thanks.
