Hi Marc, Does the problem still persist? Could you try running it with the custom Kryo serialiser that Flavio posted here: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/com-esotericsoftware-kryo-KryoException-and-java-lang-IndexOutOfBoundsException-tp7459p7461.html <http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/com-esotericsoftware-kryo-KryoException-and-java-lang-IndexOutOfBoundsException-tp7459p7461.html>
Or, better yet. Try implementing your custom type in such a way that it doesn’t need to Kryo serialiser but can work with the PojoSerializer. For this you need to ensure that the type as a zero-argument constructor and that all fields are either public or have public getters/setters. Best, Aljoscha > On 8.
