-----------------------------------
Key: PIG-1541
URL:
https://issues.apache.org/jira/browse/PIG-1541Project: Pig
Issue Type: Bug
Affects Versions: 0.7.0
Reporter: Richard Ding
Assignee: Richard Ding
Fix For: 0.8.0
Attachments: PIG-1541.patch
Here is an example:
Data input:
{code}
1 1
2
{code}
the script
{code}
a = load 'input';
b = load 'input';
c = join a by $0, b by $0 using 'repl';
dump c;
{code}
generates results that matches null values:
{code}
(1,1,1,1)
(,2,,2)
{code}
The regular join, on the other hand, gives the correct results.
