Re: kryo Serealization Exception

2016-08-22 Thread Thomas Weise 
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:

Re: kryo Serealization Exception

2016-08-20 Thread Tushar Gosavi 
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.

-Tushar.
