Pig running with thread

Question

I'm trying to load the data from the local dir to pig using the command

records = load '/home/hduser/Downloads/1901' as (year:chararray,temperature:int, quality:int);

dump records; This works fine.

while I try the next command

filtered_records = filter records by temperature != 9999 AND (quality == 0 OR quality == 1 OR quality == 4 OR quality == 5 OR quality == 9);

dump filtered_records;

This shows the following message with some thread

I think you should define your loader, like:

records = load '/home/hduser/Downloads/1901'  Using PigStorage(',') as (year:chararray,temperature:int, quality:int);

To have the data correctly in your records table according to the schem you defined. (Please use the correct loader function, if you're using a csv or tsv than update PigStorage's separator character for that what your're using in your data file)
