---------------------------------

             Summary: ExprNode/Sarg changes to support values supplied during query runtime
                 Key: HIVE-15270
                 URL: https://issues.apache.org/jira/browse/HIVE-15270
             Project: Hive
          Issue Type: Improvement
            Reporter: Jason Dere
            Assignee: Jason Dere


Infrastructure changes to support retrieval of query-runtime supplied values, needed for dynamic
min/max (HIVE-15269) and bloomfilter join optimizations.
- Some concept of available runtime values that can be retrieved for a MapWork/ReduceWork
- ExprNode/Sarg changes to pass a Conf during initialization - this allows the expression
to retrieve the MapWork at query time (using Utilities.getMapWork(Configuration)) to access
runtime-supplied values.
- Ability to populate the runtime values in Tez mode via incoming Tez edges
