------------------------------------
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.
