> Flink should support Lombok POJO
> --------------------------------
>                 Key: FLINK-6909
>                 URL: https://issues.apache.org/jira/browse/FLINK-6909
>             Project: Flink
>          Issue Type: Wish
>          Components: Type Serialization System
>            Reporter: Md Kamaruzzaman
>            Assignee: Timo Walther
>            Priority: Minor
> Project lombok helps greatly to reduce boilerplate Java Code. 
> It seems that Flink does not accept a lombok POJO as a valid pojo. 
> e.g. Here is a POJO defined with lombok:
> @Getter
> @Setter
> @NoArgsConstructor
> public class SimplePojo
> Using this Pojo class to read from CSV file throws this exception:
> Exception in thread "main" java.lang.ClassCastException: 
> org.apache.flink.api.java.typeutils.GenericTypeInfo cannot be cast to 
> org.apache.flink.api.java.typeutils.PojoTypeInfo
> It would be great if flink supports lombok POJO.
