----------------------------------------------
Summary: Simplify ExprFactory, ExprNodeDescExprFactory and
RexNodeExprFactory
Key: HIVE-23225
URL: https://issues.apache.org/jira/browse/HIVE-23225
Project: Hive
Issue Type: Improvement
Reporter: Jesus Camacho Rodriguez
The new {{ExprFactory}} was created based on existing calls from
{{TypeCheckProcFactory}}. Now that we have the {{ExprNodeDesc}} and {{RexNode}}
implementations, it seems we could do some work consolidating those methods,
simplifying the super/subclasses, etc. For instance, the handling of literal
values seems quite convoluted (handled by many different method) and could
possibly be abstracted in a different way.
