Review Comment:
@nsivabalan , I checked the code, the repair is applied in the
`adapter.getReaderSchemas` implementation, since it only applied to >= spark3.4
version.
` Pair<StructType, StructType> readerSchemas =
SparkAdapterSupport$.MODULE$.sparkAdapter().getReaderSchemas(storage,
readerSchema, requestedSchema, fileSchema);`
