  7. def clipParquetSchema(parquetSchema: MessageType, catalystSchema: StructType, caseSensitive: Boolean, useFieldId: Boolean): MessageType

    Tailors parquetSchema according to catalystSchema by removing column paths don't exist in catalystSchema, and adding those only exist in catalystSchema.

  8. def clipParquetSchema(parquetSchema: MessageType, catalystSchema: StructType, caseSensitive: Boolean = true): MessageType

    Overloaded method for backward compatibility with caseSensitive default to true and useFieldId default to false
