Review comment:

> Queryable state should check types
> ----------------------------------
>
> Key: FLINK-8058
> URL: https://issues.apache.org/jira/browse/FLINK-8058
> Project: Flink
> Issue Type: Improvement
> Components: Queryable State
> Affects Versions: 1.4.0
> Reporter: Chesnay Schepler
> Assignee: Congxian Qiu
> Priority: Major
> Labels: pull-request-available
>
> The queryable state currently doesn't do any type checks on the client or
> server and generally relies on serializers to catch errors.
> Neither the type of state is checked (ValueState, ListState etc.) nor the
> type of contained values.
