stevomitric opened a new pull request, #57965: URL: https://github.com/apache/spark/pull/57965
### What changes were proposed in this pull request? Add an end-to-end test to `TimestampNanosFunctionsSuiteBase` (run in both ANSI modes) asserting that collect_set deduplicates on the full nanosecond value: sub-microsecond-distinct values stay distinct at p=9 but collapse when floored below the grid at p in [7, 8]. Also add a deterministic golden SQL case (`sort_array(collect_set(...))`) to `timestamp-ntz-nanos.sql` / `timestamp-ltz-nanos.sql`. ### Why are the changes needed? Extend test coverage for timestamp nanosecond precision datatype. ### Does this PR introduce _any_ user-facing change? No, test only change. ### How was this patch tested? Test-only change. ### Was this patch authored or co-authored using generative AI tooling? Co-Authored-By: Claude Code 4.8 -- This is an automated message from the Apache Git Service.
