IMPALA-15237: Add Calcite regression harness
Expose the optimized logical plan immediately before Impala
conversion to same-package tests. Preserve the production optimization
path. Capture client output labels and exact Calcite types before
conversion, then verify that conversion to ImpalaPlanRel completes.
Exercise direct Calcite parsing, analysis, logical optimization, and
Impala conversion without Frontend fallback. Use synthetic tables for a
compact supported corpus covering values, filters, aggregation, sorting,
joins, unions, and analytic functions. Characterize output schemas and
percent_rank rewriting, and explicitly classify unsupported complex
types.
Testing:
- Focused Linux CMake generation and ninja fesupport/java build
- CalciteOptimizerTest: 4 tests, 0 failures, 0 errors; BUILD SUCCESS
- git diff --check

> Calcite planner: Add direct no-fallback regression harness

> Key: IMPALA-15237
> URL: https://issues.apache.org/jira/browse/IMPALA-15237
> Project: IMPALA
> Issue Type: Sub-task
> Components: Frontend
> Reporter: Aleksandr Efimov
> Assignee: Aleksandr Efimov
> Priority: Major
> Fix For: Impala 5.0.0
>
>
> Calcite planner regressions can be hidden when Frontend retries a query with
> the Original planner. Add a test-only direct planning harness that exercises
> Calcite parsing, analysis, logical optimization, and conversion without going
> through Frontend fallback.
> The harness should expose the optimized logical RelNode immediately before
> Impala conversion together with client-visible output labels and exact
> Calcite output types. Add a compact synthetic corpus covering supported
> operators and an explicitly unsupported complex-type case.
