Hi,

I am using the scala api and I want to deserialize a column in a CSV to a
custom object type. Is this possible? Here's a code snippet of something I
want to do:

val rows = env.readCsvFile[(String, CustomType)]("./test.csv",
includedFields = Array(0, 1), ignoreFirstLine = true)

When I do this I get this error: "The type 'org.example.CustomType' is not
supported for the CSV input format."

I saw that readCsvFile only supports these types:
https://github.com/apache/flink/blob/e10e548feb2bedf54c3863bbd49ed4f9140546cf/flink-core/src/main/java/org/apache/flink/types/parser/FieldParser.java

Is it possible to add custom deserializers? The only other way I thought
was to read it as a string and then map it as the custom type. I even tried
something like: env.registerTypeWithKryoSerializer(CustomType.getClass(),
new RowSer().getClass())

But I guess that api doesn't affect the CSV parser.

Thanks
