If your field type is org.joda.time.DateTime and declared thus:

DateTime jodaDateTime;

How about just adding these imports:

import com.esotericsoftware.kryo.serializers.FieldSerializer.Bind;
import de.javakaffee.kryoserializers.jodatime.JodaDateTimeSerializer;

and adding this annotation just above the field declaration, like so:

@FieldSerializer.Bind(JodaDateTimeSerializer.class)
DateTime jodaDateTime;

Thanks a lot Ram for the response.

Yes, I am relaunching with application Id.

The usage related information in the documentation links are like bit heavy for 
the knowledge I have… do we have a simple example on how to use?

By the way, I want to use JodaTime DateTime Serializer which are already 
available I believe. Any help for using DateTime JodaDateTimeSerializer() ?

Thanks a lot.

By "relaunches" I assume you mean you're launching with the previous 
application ID ?

When you do that, the platform attempts to restore state from the previously 
saved serialized form.
To do that, it needs to firstcreate the object with a no-arg constructor and 
then populate it.
If that constructor is absent, you get the exception.

Please see the section entitled "Application throwing following Kryo exception"
at 
http://docs.datatorrent.com/troubleshooting/#application-throwing-following-kryo-exception

Hi,

During application relaunches I am getting serialization exceptions like below, 
but not when launching the application for the first time ….


Caused by: com.esotericsoftware.kryo.KryoException: Class cannot be created 
(missing no-arg constructor): org.joda.time.chrono.ISOChronology
Serialization trace:
iChronology (org.joda.time.DateTime)



I am seeing these exception only when doing relaunches not for the first time 
launching!! Relaunch can be any of the scenario like, KILLED or SHUTDOWN!!


Please share you thoughts….



Regards,

Raja.
