             Summary: Update/delete/merge statements not optimized through CBO
                 Key: HIVE-22785
                 URL: https://issues.apache.org/jira/browse/HIVE-22785
             Project: Hive
          Issue Type: Improvement
          Components: CBO
            Reporter: Jesus Camacho Rodriguez


Currently, CBO is bypassed for update/delete/merge statements.

To support optimizing these statements through CBO, we need to complete three 
main tasks: 1) support for sort in CBO, 2) support for SORT in AST converter, 
and 3) {{RewriteSemanticAnalyzer}} should extend {{CalcitePlanner}} instead of 
{{SemanticAnalyzer}}.
