suppose my data has 100 columns or fields, and i want to impose a schema. is there a way i can create a separate file describing the schema of these fields, and let PIG read the schema from that file?
for example. instead of verbose typing in the pigscript.... A = load mydata as (c1:int, c2:chararray, ...... ,c100:charaaray) can i do something like. A = load mydata as described in myschema.txt myschema.txt would be something like c1: int c2: chararray .... .... c100: chararray thanks vkh
