This will not handle union followed by store right? Can we create a separate jira for that?

    Don't we have to iterate through all the values? Won't there be more than one if shuffle edge is used and input grouped?

    Can you please add a TODO to use POValueOutputTez instead of POLocalRearrange and unsorted shuffle with TEZ-661 and PIG-3775
