After HUDI-6960 is merged PR #9889, the
shouldExtractPartitionValuesFromPartitionPathwill correctly ignore partition columns inrequiredSchema.When using the configs below, there will be read errors.
The query schema will be pruned to NOT contain any partition columns.
When rebuilding parquet filters, file schema's columns are scanned against querySchema. However, Hudi files (file schema) might still contain partition columns. And when partition filters are being rebuilt with these file schema against query schema, it will lead to partition columns not being found.
