Avro uses org.apache.avro.util.Utf8 to represent strings, not
java.lang.String.

Hi guys, I am getting this error when trying to build a schema using an
existing class with ReflectData.getSchema method with a List<String>
field. Is this expected behaviour? Are List's not supported?
ptype = java.util.List<java.lang.String> raw = interface java.util.List
param =class java.lang.String
Exception in thread "main" org.apache.avro.AvroTypeException: Unknown
