This is the pig script -

%default previousPeriod $pPeriod

tWeek = LOAD '/tmp/test_data.txt' USING PigStorage ('|') AS (WEEK:int,
DESCRIPTION:chararray, END_DATE:chararray, PERIOD:int);

gTWeek = FOREACH tWeek GENERATE WEEK AS WEEK, PERIOD AS PERIOD;

*pWeek = FILTER gTWeek BY PERIOD == $previousPeriod;*

pWeekRanked = RANK pWeek BY WEEK ASC DENSE;

gpWeekRanked = FOREACH pWeekRanked GENERATE $0;
store gpWeekRanked INTO 'gpWeekRanked';
describe gpWeekRanked;
Without the filter statement, the code runs without hanging.

Cheers,
Suhas.
