IMPALA-15288: Fix test_const_only_union on calcite-planner
For const-only query "select 1 union select 2", Calcite doesn't generate
an AggregationNode over the UnionNode, which causes the test fails.
This modifies the test to add a section for the Calcite plan.
Testing
- Ran test_hbo.py locally with calcite-planner enabled.
