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

             Summary: queryable state: KvStateRequestSerializer#deserializeKeyAndNamespace() throws an IOException without own failure message if deserialisation fails
                 Key: FLINK-5559
                 URL: https://issues.apache.org/jira/browse/FLINK-5559
             Project: Flink
          Issue Type: Improvement
          Components: Queryable State
    Affects Versions: 1.2.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber
            Priority: Minor


KvStateRequestSerializer#deserializeKeyAndNamespace() throws an IOException, e.g. EOFException, if the deserialisation fails, e.g. there are not enough available bytes.
In these cases, it should instead also throw an IllegalArgumentException with a message containing "This indicates a mismatch in the key/namespace serializers used by the KvState instance and this access." as the other error cases.
