## Problem The regression test `push_down_filter_through_set_operation_with_unique_function` in `nereids_rules_p0/unique_function/` is unstable across different pipeline environments. When the cluster has only one pipeline executor (`parallel=1`), `SplitAggWithoutDistinct` skips two-phase aggregation (introduced in `b1112e5dbdc`), and `hashAgg[LOCAL]` is not generated. This causes the plan shape to diverge from the expected output: ``` Expected: ------hashAgg[LOCAL] Actual: ------PhysicalUnion ``` ## Fix Add `SET parallel_pipeline_task_num=2` to the test suite to lock non-single-instance mode, ensuring `hashAgg[LOCAL]` is always generated regardless of BE hardware. ## Related PR - #62742 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
