Nandor Kollar commented on PIG-5310:
------------------------------------
[~satishsaley] could you please help me to reproduce this issue? The test case
in your patch passes even when I *don't* apply the changes you made on
POMergeJoin.java (expecting a failing test case). I tried with
{{-Dtest.exec.type=spark}}, {{-Dtest.exec.type=tez}}, and
{{-Dtest.exec.type=mr}}, each finished successfully.
