> Simplify SemanticAnalyzer by removing unused code
> -------------------------------------------------
>
> Key: HIVE-22191
> URL: https://issues.apache.org/jira/browse/HIVE-22191
> Project: Hive
> Issue Type: Task
> Components: Hive
> Reporter: Akos Dombi
> Assignee: Akos Dombi
> Priority: Major
> Attachments: HIVE-22191.2.patch, HIVE-22191.3.patch, HIVE-22191.patch
>
>
> Simplify {{SemanticAnalyzer}} by:
> - Remove dead code
> - Simplify returning statements
> - Use interfaces types for parameters/fields/variables where it is
> straightforward to migrate
> - Make visibility stricter where it is possible
> - Check logging to use parametrised logging
> - Removing unnecessary keywords (e.g.: {{static}})
> - Some code part could be simplified by using Java 8 features
> I think this is crucial step as this class already contains 15000+ lines of
> code which is screaming for splitting into more reasonable classes.
