Fixed issues
This hotfix release of the Cloudera Data Warehouse (CDW) service on CDP Public Cloud introduces a Runtime fix.
- DWX-18477: (Addendum) Merge query failures with reserved keywords as column names
- If a reserved keyword is used as a column name in a query, you
must escape the keyword by enclosing it within backticks (`). However, If you have merge
queries involving Iceberg target tables that use reserved keywords as column names, the
backticks are not retained when the merge queries are rewritten to a join query, and the
query fails with a "SemanticException" error.
This issue is now fixed as part of an additional fix that was provided in HIVE-28282.
