I checked the logs thanks to Paul's suggestion. I see a couple interesting things. Restoring into 1.8 from a 1.4 savepoint, some TMs receive partial state (e.g. only a partition/offset pair or two per TM -- we have 8 partitions on this topic). I'm not sure if this is normal (e.g. maybe TMs only use

Re: Restore state class not found exception in 1.8

Hi Gordon We have found a solution but not why it happens on 1.8. For it to work we need to call Env.registertype(Reportmessage.class) Reportmessage extends ReportmessageBase and the state operator use ReportmessageBase. So we need to register all the class’s that extends a class used in state

Hi Gordon Thanks for the reply. No we haven’t moved it around namespaces. The only thing we have done is to add a new attribute to the object in another branch of our code and it could be we by mistake has used it but it should still not give a class not found exception. We have the save point
