-----------------------------------
Assignee: (was: Matt McCline)
> Refactor setting internal configuration properties to a single place
> --------------------------------------------------------------------
>
> Key: HIVE-12912
> URL: https://issues.apache.org/jira/browse/HIVE-12912
> Project: Hive
> Issue Type: Bug
> Components: Hive, ORC
> Reporter: Matt McCline
> Priority: Critical
>
> Currently, filters and projections are set to conf object in HiveInputFormat
> (refer pushProjectionsAndFilters). Setting config transactional table is done
> in several places (Fetchtask, SMBMapJoinOperator, MapredLocalTask etc.).
> Setting schema evolution columns is done in Utilities.
> Although all the values are available in TableScanDesc we are setting them in
> different places making it harder to track. It's better to do the all the
> following in single place (may be HiveInputFormat?)
> 1) Filters
> 2) Projection
> 3) Transactional table boolean
> 4) Schema evolution columns
