Gunther Hagleitner updated HIVE-5437:
-------------------------------------
Description:
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.
NO PRECOMMIT TESTS (this is wip for the tez branch)
