Btw, I found a way to get this to work (without enabling generic types, but
still use kyro to serialize the write result ender the hood).
First create a class called `WriteResultTypeInformation`:
```
import org.apache.flink.api.common.ExecutionConfig;
import org.apache.flink.api.common.typeinfo.TypeInfoFactory;
import org.apache.flink.api.common.typeinfo.TypeInformation;
import org.apache.flink.api.common.typeutils.TypeSerializer;
import org.apache.flink.api.java.typeutils.runtime.kryo.KryoSerializer;
import org.apache.iceberg.io.WriteResult;
import java.lang.reflect.Type;
import java.util.Map;
public class WriteResultTypeInformation extends TypeInfoFactory<WriteResult>
{
@Override
public TypeInformation<WriteResult> createTypeInfo(Type t,
Map<String, TypeInformation<?>> genericParameters) {
return new TypeInformation<>() {
@Override
public boolean isBasicType() {
return false;
}
@Override
public boolean isTupleType() {
return false;
}
@Override
public int getArity() {
return 3;
}
@Override
public int getTotalFields() {
return 3;
}
@Override
public Class<WriteResult> getTypeClass() {
return WriteResult.class;
}
@Override
public boolean isKeyType() {
return false;
}
@Override
public TypeSerializer<WriteResult>
createSerializer(ExecutionConfig config) {
return new KryoSerializer<>(this.getTypeClass(), config);
}
@Override
public String toString() {
return null;
}
@Override
public boolean equals(Object obj) {
return false;
}
@Override
public int hashCode() {
return 0;
}
@Override
public boolean canEqual(Object obj) {
return false;
}
};
}
}
```
and then in the config, put:
```
pipeline.serialization-config:
- org.apache.iceberg.io.WriteResult: {type: typeinfo, class:
org.apache.iceberg.io.WriteResultSerializer}
```
or programatically:
```
Configuration config = new Configuration();
config.set(PipelineOptions.SERIALIZATION_CONFIG,
List.of("org.apache.iceberg.io.WriteResult: {type: typeinfo,
class: org.apache.iceberg.io.WriteResultSerializer}"));
see = StreamExecutionEnvironment.getExecutionEnvironment(config);
```
