zabetak opened a new pull request, #6092: URL: https://github.com/apache/hive/pull/6092
### Why are the changes needed? Avoid interference between AST and CBO based materialization of common table expressions (CTEs). More details in HIVE-29217. ### Does this PR introduce _any_ user-facing change? Yes but highly unlikely. Users may see plan/perf changes if they set/rely on the **experimental** property `hive.optimize.cte.suggester.class` and they expect both AST and CBO materialization to trigger sequentially one after the other. ### How was this patch tested? Existing plus new tests. ``` mvn test -Dtest=TestMiniLlapLocalCliDriver -Dqfile_regex=.*cte.* mvn test -Dtest=TestTezTPCDS30TBPerfCliDriver ``` -- This is an automated message from the Apache Git Service.
