------------------------------------------
Summary: Deprecate hive.cbo.fallback.strategy property
Key: HIVE-28741
URL: https://issues.apache.org/jira/browse/HIVE-28741
Project: Hive
Issue Type: Task
Reporter: Stamatis Zampetakis
Assignee: Stamatis Zampetakis
At the moment, the default value of this property is NEVER which means that CBO
errors are fatal. After HIVE-27831, there are no known issues that require CBO
to fallback to the legacy optimizer so we don't need this property anymore. We
should deprecate the property in this release and remove it completely in the
next one.
Users should not change the default value of this property as there are no
plans to maintain the fallback behavior. In case of CBO failures, users are
highly encouraged to log new tickets.
