I agree that it is more appropriate to throw the `IOException`.
> 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.
