   @kazuyukitanimura Thanks for working on this! 
   
   I took a look at how Iceberg handles FLBA. For iceberg type `Types.FixedType`, the underneath Parquet type is `fixed_len_byte_array`. In `Scan.readSchema`, Iceberg map `Types.FixedType` to Spark `BinaryType`. Since FLBA is a valid parquet data type, it makes sense to me for Spark support this type and map it to `BinaryType`.
