------------------------------------

             Summary: Check parameters for serializability before sending a remote RpcInvocation message
                 Key: FLINK-4383
                 URL: https://issues.apache.org/jira/browse/FLINK-4383
             Project: Flink
          Issue Type: Sub-task
            Reporter: Till Rohrmann


Before sending a remote {{RpcInvocation}} message we should check that the rpc arguments are serializable. If not we should eagerly fail with an appropriate exception message.

If we don't do this, then Akka will silently fail serializing the message without telling the user.
