      Description

      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
