Steve Carlin created HIVE-22408: ----------------------------------- Summary: The fix for CALCITE-2991 creates wrong results on edge case Key: HIVE-22408 URL: https://issues.apache.org/jira/browse/HIVE-22408 Project: Hive Issue Type: Bug Components: CBO Affects Versions: 3.1.2 Reporter: Steve Carlin Assignee: Vineet Garg
The Calcite upgrade from 1.19 to 1.21 includes a fix for CALCITE-2991. This patch causes a failure in subquery_ALL.q In order to proceed with the upgrade, the patch was bypassed by creating the HiveRelMdMaxRowCount class which overrides the behavior in Calcite. In order to recreate the regression, remove this file and the references to the class in HiveDefaultRelMetadataProvider. This Jira is being created before the HIVE-22274 PR has been pushed, so please wait until that is pushed before working on this. -- This message was sent by Atlassian Jira (v8.3.4#803005)
