Giambattista Bloisi created SPARK-44910:
-------------------------------------------
Summary: Encoders.bean does not support superclasses with generic
type arguments
Key: SPARK-44910
URL: https://issues.apache.org/jira/browse/SPARK-44910
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.4.1, 3.5.0, 4.0.0
Reporter: Giambattista Bloisi
As per SPARK-44634 another unsupported feature of bean encoder is when the
superclass of the bean has generic type arguments. For example:
{code:java}
class JavaBeanWithGenericsA<T> {
public T getPropertyA() {
return null;
}
public void setPropertyA(T a) {
}
}
class JavaBeanWithGenericBase extends JavaBeanWithGenericsA<String> {
}
Encoders.bean(JavaBeanWithGenericBase.class); // Exception
{code}
