zhengruifeng opened a new pull request, #57757: URL: https://github.com/apache/spark/pull/57757
### What changes were proposed in this pull request? This draft reuses `SQLDataTypes.VectorType` instead of creating equivalent `VectorUDT` instances throughout the ML implementation. ### Why are the changes needed? `VectorUDT` is stateless. Reusing the canonical ML vector data type avoids repeated equivalent allocations and keeps schema checks and output schemas consistent. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? `build/sbt mllib/compile` completed successfully. The test suite was not run. ### Was this patch authored or co-authored using generative AI tooling?
