Summary: Split up UpdateDeleteSemanticAnalyzer
Key: HIVE-20919
URL: https://issues.apache.org/jira/browse/HIVE-20919
Project: Hive
Issue Type: Improvement
Components: Hive
Affects Versions: 3.2.0
Reporter: Miklos Gergely
Assignee: Miklos Gergely
Fix For: 3.2.0
UpdateDeleteSemanticAnalyzer handles update, delete, acid export and merge
queries by rewriting them to a different form. This is a clear violation of
[SRP|[https://en.wikipedia.org/wiki/Single_responsibility_principle],] and
therefore needs to be refactored. An abstract ancestor needs to take the common
part, and each of the specific tasks should be handled by a separate class.
