------------------------------------------------------------------------------------------
Key: PIG-1963
URL: https://issues.apache.org/jira/browse/PIG-1963
Project: Pig
Issue Type: Bug
Affects Versions: 0.8.0, 0.9.0
Reporter: Thejas M Nair
This happens only when secondary sort is not being used for the order-by.
For example -
{code}
a1 = load 'fruits.txt' as (f1:int,f2);
a2 = load 'fruits.txt' as (f1:int,f2);
b = cogroup a1 by f1, a2 by f1;
d = foreach b {
sort1 = order a1 by f2;
sort2 = order a2 by f2; -- secondary sort not getting used here, MYCONCATBAG
gets results in wrong order
generate group, MYCONCATBAG(sort1.f1), MYCONCATBAG(sort2.f2);
}
-- explain d;
dump d;
{code}
