     [ https://issues.apache.org/jira/browse/PIG-5201?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Koji Noguchi updated PIG-5201:
------------------------------
    Attachment: pig-5201-v00-testonly.patch

Attaching a unit test I'm using for testing FLATTEN(null) and FLATTEN(bag-with-null). 

Please ignore the expected results part.  For that, I'm waiting for feedback from others like [~rohini], [~daijy], etc.
