### What changes were proposed in this pull request? This PR proposes to improve error message for `assertSchemaEqual` ### Why are the changes needed? Current error message is not very actionable and lack of detail when the given parameter has invalid data type: ```python >>> assertSchemaEqual(df, df) # Should be `df.schama` instead of `df` [UNSUPPORTED_DATA_TYPE] Unsupported DataType `<class 'pyspark.sql.classic.dataframe.DataFrame'>`. ``` ### Does this PR introduce _any_ user-facing change? No API change, but there is some user-facing error message change: **Before** ```python [UNSUPPORTED_DATA_TYPE] Unsupported DataType `<class 'pyspark.sql.classic.dataframe.DataFrame'>`. ``` **After** ```python [NOT_STRUCT] Argument `actual` should be a struct type, got DataFrame. ``` ### How was this patch tested? The existing CI should pass ### Was this patch authored or co-authored using generative AI tooling? No -- This is an automated message from the Apache Git Service.
