------------------------------------

             Summary: Add ROW__ID VirtualColumn
                 Key: HIVE-7513
                 URL: https://issues.apache.org/jira/browse/HIVE-7513
             Project: Hive
          Issue Type: Sub-task
          Components: Query Processor
    Affects Versions: 0.13.1
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman


In order to support Update/Delete we need to read rowId from AcidInputFormat and pass that
along through the operator pipeline (built from the WHERE clause of the SQL Statement) so
that it can be written to the delta file by the update/delete (sink) operators.

The parser will add this column to the projection list to make sure it's passed along.
