HeartSaVioR opened a new pull request #30033: URL: https://github.com/apache/spark/pull/30033
### What changes were proposed in this pull request? This PR proposes to fix a bug on calling `DataType.equalsIgnoreCompatibleNullability` with mistakenly swapped parameters in `V2WriteCommand.outputResolved`. The order of parameters for `DataType.equalsIgnoreCompatibleNullability` are `from` and `to`, which says that the right order of matching variables are `inAttr` and `outAttr`. ### Why are the changes needed? Spark throws AnalysisException due to unresolved operator in v2 write, while the operator is unresolved due to a bug that parameters to call `DataType.equalsIgnoreCompatibleNullability` in `outputResolved` have been swapped. ### Does this PR introduce _any_ user-facing change? Yes, end users no longer suffer on unresolved operator in v2 write if they're trying to write dataframe containing non-nullable complex types against table matching complex types as nullable. ### How was this patch tested? New UT added. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
