### What changes were proposed in this pull request? Support Barrier Python UDF, we could support it in general, but right now I want to narrow its usage scope because it is only used in Torch Distributor for now: - it is supported as a function attribute, without adding a user-facing API or Parameter; - it only works in `MapInPandas` and `MapInArrow` ### Why are the changes needed? Barrier should be an UDF attribute ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? existing UTs -- This is an automated message from the Apache Git Service.
