Hi, I use flink-scala version 1.9.1 and scala 2.12.10, and I defined a data type which is a bit more complex: it has a list in it and even a dictionary. When I try to use a custom map I got this error:
INFO org.apache.flink.api.java.typeutils.TypeExtractor - class A does not contain a setter for field fields INFO org.apache.flink.api.java.typeutils.TypeExtractor - class A cannot be used as a POJO type because not all fields are valid POJO fields, and must be processed as GenericType. Please read the Flink documentation on "Data Types & Serialization" for details of the effect on performance. Is there a fix for this? Or a workaround? Thank you, Alex
