             Summary: Add map/reduce input map to MapWork/ReduceWork for multi input
                 Key: HIVE-5437
                 URL: https://issues.apache.org/jira/browse/HIVE-5437
             Project: Hive
          Issue Type: Bug
            Reporter: Gunther Hagleitner
            Assignee: Gunther Hagleitner
             Fix For: tez-branch


When there are multiple incoming edges to the tezprocessor we'll need to be able to tell which
alias or tag they belong to.

In the map case:

- Potentially multiple MRInputs. Need to map those to aliases/operators

In the reduce case:

- Each tag will be represented by a logical input. We need to know which table each input
belongs to.
