Pig Local give wrong results
----------------------------
Key: PIG-248
URL: https://issues.apache.org/jira/browse/PIG-248
Project: Pig
Issue Type: Bug
Environment: Pig Local
Reporter: Amir Youssefi
Pig Local mode gives wrong results (but Pig + Hadoop give correct results) .
This created issues for users who tried to debug in local mode...
Here's my pig code:
a = load '/homes/amiry/tmp/my_test.txt' as (c1,c2,c3);
b = group a by c1;
c = foreach b {
d = order a by c3;
generate d;
}
dump c;
Pig + Hadoop:
({(abc, http://www.sss.net, a), (abc, http://www.rrr.com, b)})
({(def, http://local.yahoo.com/, d), (def, http://lmn.com/, f), (def,
http://xyz.com/, g)})
Pig Local:
({(abc, http://www.sss.net, a), (abc, http://www.rrr.com, b)})
({})
Input:
abc http://www.rrr.com b
abc http://www.sss.net a
def http://local.yahoo.com/ d
def http://lmn.com/ f
def http://xyz.com/ g
