FR Join shouldn't match null values
-----------------------------------

                 Key: PIG-1541
                 URL: https://issues.apache.org/jira/browse/PIG-1541
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.7.0
            Reporter: Richard Ding
            Assignee: Richard Ding
             Fix For: 0.8.0



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.
