[jira] [Updated] (HIVE-5437) Add map/reduce input map to
MapWork/ReduceWork for multi input
[ https://issues.apache.org/jira/browse/HIVE-5437?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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)
