Adnan Khan commented on FLINK-1388:
-----------------------------------

Hey Timo,

So the rules for defining a POJO according to 
[this|https://github.com/apache/flink/blob/master/docs/internal_types_serialization.md]
 include this part {quote} All fields in the class (and all superclasses) are 
either public or or have a public getter and a setter method that follows the 
Java beans naming conventions for getters and setters. {quote}

So that means that it could have private fields. I was thinking we should add 
{{field.setAccessible(true)}} in the implementation for {{PojoField}}. 
Otherwise something like {{pFieldValue = pField.field.get(myPojo)}} does not 
seem to work.

I ran into while I was testing the CSV writer with POJOs with private fields 
but public getter/setters.

> It would be great if one could simply write out POJOs in CSV format.

> public class MyPojo {
>    String a;
>    int b;
> }

> {code}
> # CSV file of org.apache.flink.MyPojo: String a, int b
> "Hello World", 42
> "Hello World 2", 47
> ...
> {code}
