> In Pig contrib project zebra,
>  When user do the union of the sorted tables, the resulting table contains a virtual
column called  'source_table'.
> Which allows user to know the original table name from where the content of the row of
the result table is coming from.
> This feature is also very useful for the case when the input tables are not sorted.
> Based on the discussion with the zebra dev team, it should be easy to implement.
> I am filing this enhancemnet jira for zebra.
