yanghua commented on issue #6876: [FLINK-10251] Handle oversized response
messages in AkkaRpcActor
URL: https://github.com/apache/flink/pull/6876#issuecomment-431640196
hi @tillrohrmann There is a problem about sending serialized data. For
example, `testNoSlotSharingAndBlockingResultReceiver` will trigger
`allocateSlot` rpc call, the result type is `SingleLogicalSlot` which has a
field `private final CompletableFuture<Void> releaseFuture`. The field caused
serialization error :
```
Caused by: org.apache.flink.runtime.rpc.akka.exceptions.AkkaRpcException:
Failed to serialize the result for RPC call : allocateSlot.
at
org.apache.flink.runtime.rpc.akka.AkkaRpcActor.serializeResultAndVerifySize(AkkaRpcActor.java:335)
at
org.apache.flink.runtime.rpc.akka.AkkaRpcActor.lambda$handleRpcInvocation$1(AkkaRpcActor.java:280)
... 33 more
Caused by: java.io.NotSerializableException:
java.util.concurrent.CompletableFuture
```

> The {{AkkaRpcActor}} should check whether an RPC response which is sent to a
> remote sender does not exceed the maximum framesize of the underlying
> {{ActorSystem}}. If this is the case we should fail fast instead. We can
> achieve this by serializing the response and sending the serialized byte
> array.
