BinaryType support in Spark with Scala - scala

Question

Good day!
I am using Microsoft Contoso BI Demo Dataset for Retail Industry database # https://www.microsoft.com/en-us/download/confirmation.aspx?id=18279 which I extract to Azure Data Lake using sqoop as bzip2 csv files "\t"-delimited
Then I convert these files to Parquet using Spark over Scala as follows:
//-------DimGeography-------
val schemaDimGeography=StructType(Array(StructField("GeographyKey",IntegerType,false),StructField("GeographyType",StringType,false),StructField("ContinentName",StringType,false),StructField("CityName",StringType,true),StructField("StateProvinceName",StringType,true),StructField("RegionCountryName",StringType,true),StructField("Geometry",BinaryType,true),StructField("ETLLoadID",IntegerType,true),StructField("LoadDate",TimestampType,true),StructField("UpdateDate",TimestampType,true)));
val dfDimGeography= spark.
read.format("com.databricks.spark.csv").
option("header", "false").
option("nullValue", "null").
option("delimiter", "\t").
schema(schemaDimGeography).
load("adl://yvtazuredatalakestore.azuredatalakestore.net/clusters/yvthdisqoop/ContosoRetailDW/Full/Bzip2/DimGeography/*.bz2");
//dfDimGeography.show();
dfDimGeography.write.mode("overwrite").parquet("adl://yvtazuredatalakestore.azuredatalakestore.net/clusters/yvthdisqoop/ContosoRetailDW/Full/Parquet2/DimGeography/");
However, it seems like because of BinaryType column Geometry I get the exception: Caused by: java.lang.RuntimeException: Unsupported type: binary
While this works perfectly fine in PySpark. Is there something I am missing to set/enable as option in Scala to handle csv with binary data as one of columns?
Full exception:

Answer 1

BinaryType is not supported for csv data source at all (Java, Scala, Python, R). The supported types are:
ByteType | ShortType | IntegerType | LongType | FloatType |
DoubleType | BooleanType |DecimalType | TimestampType |
DateType | StringType
You'll have to parse this data manually.
