[jira] [Created] (HIVE-2339) Preserve RS key columns in
columnExprMap in CP, which might be useful to other optimizers
Preserve RS key columns in columnExprMap in CP, which might be useful to other optimizers
-----------------------------------------------------------------------------------------
Key: HIVE-2339
URL: https://issues.apache.org/jira/browse/HIVE-2339
Project: Hive
Issue Type: Sub-task
Reporter: Navis
Priority: Trivial
In ColumnPrunerProcFactory#pruneReduceSinkOperator, only VALUE parts are retained from columnExprMap. Doesn't anyone want KEY parts to retained, either? In my case, it was very useful for backtracking column names and removing RS in *-RS-*-RS-GBY case.

[jira] [Reopened] (HIVE-2339) Preserve RS key columns in

Navis reopened HIVE-2339:

It seemed to be fixed by HIVE-1989. It was true for join cases but for group-by cases, mapping information of keys are still missing.
