Hi ,
I am trying to use java serialization as per below but launch is failing with
below exception. I am using the below annotation on the operator class. Any
thoughts?
@DefaultSerializer(JavaSerializer.class)
public class AvroFileOutputOperator extends
GroupFileOutputOperator<GenericRecord> {
//some code
############### Exception ########################3
An error occurred trying to launch the application. Server message:

There is some information available here:
http://docs.datatorrent.com/troubleshooting/#application-throwing-following-kryo-exception
If the object is Java serializable, you can set the stream codec or wrap into
KryoJdkContainer:

Hi Tushar,
In Our case, Generic Record fields are generated at run time from database. I
cannot convert into a predefined POJO to pass through output port.
Is it mandatory that Generic Record class must have no-arg constructor for kryo
serialization ?
Regards,
Surya Vamshi

Hi
Another option is to create your own Java object and populate the fields you
need for further processing from GenericRecord, and send it on the output port.
You can use this approach if you can not put the operators in single container,
because 1) you need to shuffle based on key or 2) resource constraints.
