Summary: Remove swapping logic to merge joins in AST converter Key: HIVE-23162 URL: https://issues.apache.org/jira/browse/HIVE-23162 Project: Hive Issue Type: Bug Components: CBO Reporter: Jesus Camacho Rodriguez Assignee: Jesus Camacho Rodriguez In ASTConverter, there is some logic to invert join inputs so the logic to merge joins in SemanticAnalyzer kicks in. https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/calcite/translator/ASTConverter.java#L407 There is a bug because inputs are swapped but the schema is not. However, it turns out that logic is not needed now that merging is off by default. -- This message was sent by Atlassian Jira (v8.3.4#803005)
