[jira] [Created] (PIG-4690) Union with self replicate join will fail in Tez

Rohini Palaniswamy created PIG-4690:
---------------------------------------

             Summary: Union with self replicate join will fail in Tez
                 Key: PIG-4690
                 URL: https://issues.apache.org/jira/browse/PIG-4690
             Project: Pig
          Issue Type: Bug
            Reporter: Rohini Palaniswamy


Found this while trying to get a reproducible script for a different issue. Not a user reported one as probability of such a script is less. Script to reproduce. 

A = LOAD 'x';
B = LOAD 'y';
C = UNION A, B;
D = JOIN C, A using 'repl';
DUMP D;

Real world scripts most likely have some foreach or filter statements before the self-join.
