zabetak opened a new pull request #1875: URL: https://github.com/apache/hive/pull/1875
### What changes were proposed in this pull request? 1. Add `hive.cbo.fallback.strategy` and plug it to the planner 2. Replace usage of `hive.in.test` in planner with `hive.cbo.fallback.strategy` ### Why are the changes needed? 1. Provide the means to fail-fast when CBO failures appear (even in production) 2. Allow finer control on tests requiring to fail on CBO, legacy, or both ### Does this PR introduce _any_ user-facing change? No at its current state. I was thinking to even drop the `CONSERVATIVE` option. The CBO error is always logged (not hidden) so I don't see why we should complicate the decision more. ### How was this patch tested? If we agree on the approach, I will add some tests for all options. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
