Hi, thanks for the update! This is really good progress!
I had a look at your code and noticed a few things apart from the inline
comments.
- PojoTypeInformation is unfortunately not serializable (as I had to learn
a few days ago myself) because ``java.lang.reflect.Field`` is not serializable.
So the InputFormat will not work if used in a complete Flink program. What you
need to do to get the IF working is to add member variables for the POJO class
and all field names. In the ``open()`` method you need to create the ``Field``
objects with ``clazz.getDeclaredField(fieldName)`` and use these fields in the
``readRecord`` method.
- Add (at least) two end-to-end tests for the Java API and the Scala API
that use the new Pojo feature. These tests will catch the TypeInformation
serialization problem.
Please don't hesitate to get in touch if you have any questions!
