Re: Failed to serialize remote message [class org.apache.flink.runtime.messages.JobManagerMessages$JobFound
I think i found the issue. I'd just like to verify that my reasoning is correct We had the following keys in our flink-conf.yaml jobmanager.web.address: localhost jobmanager.web.port: 8081 This worked on flink 1.3.2 But on flink 1.4.0 this check https://github.com/apache/flink/blob/32770103253e01cd61c8634378cfa1b26707e19a/flink-runtime/src/main/java/org/apache/flink/runtime/rest/handler/util/HandlerRedirectUtils.java#L62 Will make make it so that both master and standby think that they don't need to perform a redirect. Which means that the standby node will serve web traffic. I am assuming that it is intended that this never happens.

Re: Failed to serialize remote message [class org.apache.flink.runtime.messages.JobManagerMessages$JobFound
Hi, this indeed indicates that a REST handler is requesting the ExecutionGraph from a JobManager which does not run in the same ActorSystem. Could you please tell us the exact HA setup. Are your running Flink on Yarn with HA or do you use standalone HA with standby JobManagers? It would be really helpful if you could also share the logs with us.

Re: Failed to serialize remote message [class org.apache.flink.runtime.messages.JobManagerMessages$JobFound
IMHO, this looks like a bug and it makes sense that you only see this with an HA setup: The JobFound message contains the ExecutionGraph which, however, does not implement the Serializable interface. Without HA, when browsing the web interface, this message is (probably) not serialized since it is only served to you via HTML. For HA, this may come from another JobManager than the Web interface you are browsing. I'm including Till (cc'd) as he might know more.
