[jira] [Updated] (PIG-5201) Null handling on FLATTEN

     [ 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-v01.patch

I have little understanding on the back-end side so this may be off.
Tried grabbing the number of fields at compile time and using it at runtime when null is passed for flatten.
