    Description

      Originally introduced for Tez, ConvertJoinMapJoin heavily uses OptimizeTezProcContext . Although we do have an equivalent OptimizeSparkProcContext, the 2 are not derived from any common ancestor class. We will need some class hierarchy redesign/refactoring to make ConvertJoinMapJoin be more generic to support multiple execution frameworks .
