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 Ram On Mon, Jun 20, 2016 at 1:32 PM, Raja.Aravapalli <[email protected] > wrote: > > 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!!
