    Description

      When parsing A OR B OR C, hive converts it into

      (C OR B) OR A

      instead of turning it into

      A OR (B OR C)

              GenericUDFOPOr or = new GenericUDFOPOr();
              List<ExprNodeDesc> expressions = new ArrayList<ExprNodeDesc>(2);
              expressions.add(previous);
              expressions.add(current);
